-LP32 ABI bugs
--------------
+Attaching GDB to the tests
+--------------------------
+
+Bionic's test runner will run each test in its own process by default to prevent
+tests failures from impacting other tests. This also has the added benefit of
+running them in parallel, so they are much faster.
+
+However, this also makes it difficult to run the tests under GDB. To prevent
+each test from being forked, run the tests with the flag `--no-isolate`.

+32-bit ABI bugs
+---------------
 
 This probably belongs in the NDK documentation rather than here, but these
-are the known ABI bugs in LP32:

- * `time_t` is 32-bit. <http://b/5819737>
+ * `time_t` is 32-bit. <http://b/5819737>. In the 64-bit ABI, time_t is

- * `off_t` is 32-bit. There is `off64_t`, but no `_FILE_OFFSET_BITS` support.
-   Many of the `off64_t` functions are missing in older releases, and
-   stdio uses 32-bit offsets, so there's no way to fully implement
-   `_FILE_OFFSET_BITS`.
+ * `off_t` is 32-bit. There is `off64_t`, and in newer releases there is
+   almost-complete support for `_FILE_OFFSET_BITS`. Unfortunately our stdio
+   implementation uses 32-bit offsets and -- worse -- function pointers to
+   functions that use 32-bit offsets, so there's no good way to implement
+   the last few pieces <http://b/24807045>. In the 64-bit ABI, off_t is
+   off64_t.
 
  * `sigset_t` is too small on ARM and x86 (but correct on MIPS), so support

- *    This test reports the overhead of the underlying futex wake syscall on
- * the producer. It does not report the overhead from issuing the wake to the
- * point where the posted consumer thread wakes up. It suffers from
- * clock_gettime syscall overhead. Lock the CPU speed for consistent results
- * as we may not reach >50% cpu utilization.
- *
- *    We will run a background thread that catches the sem_post wakeup and
- * loops immediately returning back to sleep in sem_wait for the next one. This
- * thread is run with policy SCHED_OTHER (normal policy), a middle policy.

-// malloc leak detection code, implemented in libc_malloc_debug.so also
-// requires access to these variables and routines (to fill allocation entry

- * Contains implementation of memory allocation routines instrumented for

- * memory leaks, buffer overruns, etc.
- * Code, implemented here is intended to run in the emulated environment only,
- * and serves simply as hooks into memory allocation routines. Main job of this
- * code is to notify the emulator about memory being allocated/deallocated,
- * providing information about each allocation. The idea is that emulator will
- * keep list of currently allocated blocks, and, knowing boundaries of each
- * block it will be able to verify that ld/st access to these blocks don't step
- * over boundaries set for the user. To enforce that, each memory block
- * allocated by this code is guarded with "prefix" and "suffix" areas, so
- * every time emulator detects access to any of these guarding areas, it can be
- * considered as access violation.

+ *  SYSEXITS.H -- Exit status codes for system programs.
+ *
+ *	This include file attempts to categorize possible error
+ *	exit statuses for system programs, notably delivermail
+ *	and the Berkeley network.
+ *
+ *	Error numbers begin at EX__BASE to reduce the possibility of
+ *	clashing with other exit statuses that random programs may
+ *	already return.  The meaning of the codes is approximately
+ *	as follows:
+ *
+ *	EX_USAGE -- The command was used incorrectly, e.g., with
+ *		the wrong number of arguments, a bad flag, a bad
+ *		syntax in a parameter, or whatever.
+ *	EX_DATAERR -- The input data was incorrect in some way.
+ *		This should only be used for user's data & not
+ *		system files.
+ *	EX_NOINPUT -- An input file (not a system file) did not
+ *		exist or was not readable.  This could also include
+ *		errors like "No message" to a mailer (if it cared
+ *		to catch it).
+ *	EX_NOUSER -- The user specified did not exist.  This might
+ *		be used for mail addresses or remote logins.
+ *	EX_NOHOST -- The host specified did not exist.  This is used
+ *		in mail addresses or network requests.
+ *	EX_UNAVAILABLE -- A service is unavailable.  This can occur
+ *		if a support program or file does not exist.  This
+ *		can also be used as a catchall message when something
+ *		you wanted to do doesn't work, but you don't know
+ *		why.
+ *	EX_SOFTWARE -- An internal software error has been detected.
+ *		This should be limited to non-operating system related
+ *		errors as possible.
+ *	EX_OSERR -- An operating system error has been detected.
+ *		This is intended to be used for such things as "cannot
+ *		fork", "cannot create pipe", or the like.  It includes
+ *		things like getuid returning a user that does not
+ *		exist in the passwd file.
+ *	EX_OSFILE -- Some system file (e.g., /etc/passwd, /var/run/utmp,
+ *		etc.) does not exist, cannot be opened, or has some
+ *		sort of error (e.g., syntax error).
+ *	EX_CANTCREAT -- A (user specified) output file cannot be
+ *		created.
+ *	EX_IOERR -- An error occurred while doing I/O on some file.
+ *	EX_TEMPFAIL -- temporary failure, indicating something that
+ *		is not really an error.  In sendmail, this means
+ *		that a mailer (e.g.) could not create a connection,
+ *		and the request should be reattempted later.
+ *	EX_PROTOCOL -- the remote system returned something that
+ *		was "not possible" during a protocol exchange.
+ *	EX_NOPERM -- You did not have sufficient permission to
+ *		perform the operation.  This is not intended for
+ *		file system problems, which should use EX_NOINPUT or
+ *		EX_CANTCREAT, but rather for higher level permissions.
+ *	EX_CONFIG -- Something was found in an unconfigured or
+ *		misconfigured state.

+Malloc Debug
+============
+
+Malloc debug is a method of debugging native memory problems. It can help
+detect memory corruption, memory leaks, and use after free issues.
+
+Currently, malloc debug requires root to enable. When it is enabled, it works
+by adding a shim layer that replaces the normal allocation calls. The replaced
+calls are:
+
+<pre>
+malloc
+free
+calloc
+realloc
+posix_memalign
+memalign
+malloc_usable_size
+</pre>
+
+On 32 bit systems, these two deprecated functions are also replaced:
+
+<pre>
+pvalloc
+valloc
+</pre>
+
+Any errors detected by the library are reported in the log.
+
+Controlling Malloc Debug Behavior
+---------------------------------
+Malloc debug is controlled by individual options. Each option can be enabled
+individually, or in a group of other options. Every single option can be
+combined with every other option.
+
+Option Descriptions
+-------------------
+### front\_guard[=SIZE\_BYTES]
+Enables a small buffer placed before the allocated data. This is an attempt
+to find memory corruption occuring to a region before the original allocation.
+On first allocation, this front guard is written with a specific pattern (0xaa).
+When the allocation is freed, the guard is checked to verify it has not been
+modified. If any part of the front guard is modified, an error will be reported
+in the log indicating what bytes changed.
+
+If the backtrace option is also enabled, then any error message will include
+the backtrace of the allocation site.
+
+If SIZE\_BYTES is present, it indicates the number of bytes in the guard.
+The default is 32 bytes, the max bytes is 16384. SIZE\_BYTES will be
+padded so that it is a multiple of 8 bytes on 32 bit systems and 16 bytes
+on 64 bit systems to make sure that the allocation returned is aligned
+properly.
+
+This option adds a special header to all allocations that contains the guard
+and information about the original allocation.
+
+Example error:
+
+<pre>
+04-10 12:00:45.621  7412  7412 E malloc_debug: +++ ALLOCATION 0x12345678 SIZE 100 HAS A CORRUPTED FRONT GUARD
+04-10 12:00:45.622  7412  7412 E malloc_debug:   allocation[-32] = 0x00 (expected 0xaa)
+04-10 12:00:45.622  7412  7412 E malloc_debug:   allocation[-15] = 0x02 (expected 0xaa)
+</pre>
+
+### rear\_guard[=SIZE\_BYTES]
+Enables a small buffer placed after the allocated data. This is an attempt
+to find memory corruption occuring to a region after the original allocation.
+On first allocation, this rear guard is written with a specific pattern (0xbb).
+When the allocation is freed, the guard is checked to verify it has not been
+modified. If any part of the rear guard is modified, an error will be reported
+in the log indicating what bytes changed.
+
+If SIZE\_BYTES is present, it indicates the number of bytes in the guard.
+The default is 32 bytes, the max bytes is 16384.
+
+This option adds a special header to all allocations that contains
+information about the original allocation.
+
+Example error:
+
+<pre>
+04-10 12:00:45.621  7412  7412 E malloc_debug: +++ ALLOCATION 0x12345678 SIZE 100 HAS A CORRUPTED REAR GUARD
+04-10 12:00:45.622  7412  7412 E malloc_debug:   allocation[130] = 0xbf (expected 0xbb)
+04-10 12:00:45.622  7412  7412 E malloc_debug:   allocation[131] = 0x00 (expected 0xbb)
+</pre>
+
+### guard[=SIZE\_BYTES]
+Enables both a front guard and a rear guard on all allocations.
+
+If SIZE\_BYTES is present, it indicates the number of bytes in both guards.
+The default is 32 bytes, the max bytes is 16384.
+
+### backtrace[=MAX\_FRAMES]
+Enable capturing the backtrace of each allocation site.
+This option will slow down allocations by an order of magnitude. If the
+system runs too slowly with this option enabled, decreasing the maximum number
+of frames captured will speed the allocations up.
+
+Note that any backtrace frames that occur within the malloc backtrace library
+itself are not recorded.
+
+If MAX\_FRAMES is present, it indicates the maximum number of frames to
+capture in a backtrace. The default is 16 frames, the maximumum value
+this can be set to is 256.
+
+This option adds a special header to all allocations that contains the
+backtrace and information about the original allocation.
+
+### backtrace\_enable\_on\_signal[=MAX\_FRAMES]
+Enable capturing the backtrace of each allocation site. If the
+backtrace capture is toggled when the process receives the signal
+SIGRTMAX - 19 (which is 45 on most Android devices). When this
+option is used alone, backtrace capture starts out disabled until the signal
+is received. If both this option and the backtrace option are set, then
+backtrace capture is enabled until the signal is received.
+
+If MAX\_FRAMES is present, it indicates the maximum number of frames to
+capture in a backtrace. The default is 16 frames, the maximumum value
+this can be set to is 256.
+
+This option adds a special header to all allocations that contains the
+backtrace and information about the original allocation.
+
+### fill\_on\_alloc[=MAX\_FILLED\_BYTES]
+Any allocation routine, other than calloc, will result in the allocation being
+filled with the value 0xeb. When doing a realloc to a larger size, the bytes
+above the original usable size will be set to 0xeb.
+
+If MAX\_FILLED\_BYTES is present, it will only fill up to the specified number
+of bytes in the allocation. The default is to fill the entire allocation.
+
+### fill\_on\_free[=MAX\_FILLED\_BYTES]
+When an allocation is freed, fill it with 0xef.
+
+If MAX\_FILLED\_BYTES is present, it will only fill up to the specified number
+of bytes in the allocation. The default is to fill the entire allocation.
+
+### fill[=MAX\_FILLED\_BYTES]
+This enables both the fill\_on\_alloc option and the fill\_on\_free option.
+
+If MAX\_FILLED\_BYTES is present, it will only fill up to the specified number
+of bytes in the allocation. The default is to fill the entire allocation.
+
+### expand\_alloc[=EXPAND\_BYTES]
+Add an extra amount to allocate for every allocation.
+
+If XX is present, it is the number of bytes to expand the allocation by.
+The default is 16 bytes, the max bytes is 16384.
+
+### free\_track[=ALLOCATION\_COUNT]
+When a pointer is freed, do not free the memory right away, but add it to
+a list of freed allocations. In addition to being added to the list, the
+entire allocation is filled with the value 0xef, and the backtrace at
+the time of the free is recorded. The backtrace recording is completely
+separate from the backtrace option, and happens automatically if this
+option is enabled. By default, a maximum of 16 frames will be recorded,
+but this value can be changed using the free\_track\_backtrace\_num\_frames
+option. It can also be completely disabled by setting the option to zero.
+See the full description of this option below.
+
+When the list is full, an allocation is removed from the list and is
+checked to make sure that none of the contents have been modified since
+being placed on the list. When the program terminates, all of the allocations
+left on the list are verified.
+
+If ALLOCATION\_COUNT is present, it indicates the total number of allocations
+in the list. The default is to record 100 freed allocations, the max
+allocations to record is 16384.
+
+This option adds a special header to all allocations that contains
+information about the original allocation.
+
+Example error:
+
+<pre>
+04-15 12:00:31.304  7412  7412 E malloc_debug: +++ ALLOCATION 0x12345678 USED AFTER FREE
+04-15 12:00:31.305  7412  7412 E malloc_debug:   allocation[20] = 0xaf (expected 0xef)
+04-15 12:00:31.305  7412  7412 E malloc_debug:   allocation[99] = 0x12 (expected 0xef)
+04-15 12:00:31.305  7412  7412 E malloc_debug: Backtrace at time of free:
+04-15 12:00:31.305  7412  7412 E malloc_debug:           #00  pc 00029310  /system/lib/libc.so

+</pre>
+
+In addition, there is another type of error message that can occur if
+an allocation has a special header applied, and the header is corrupted
+before the verification occurs. This is the error message that will be found
+in the log:
+
+<pre>
++++ ALLOCATION 0x12345678 HAS CORRUPTED HEADER TAG 0x1cc7dc00 AFTER FREE
+</pre>
+
+### free\_track\_backtrace\_num\_frames[=MAX\_FRAMES]
+This option only has meaning if free\_track is set. It indicates how many
+backtrace frames to capture when an allocation is freed.
+
+If MAX\_FRAMES is present, it indicates the number of frames to capture.
+If the value is set to zero, then no backtrace will be captured when the
+allocation is freed. The default is to record 16 frames, the max number of
+frames to to record is 256.
+
+### leak\_track
+Track all live allocations. When the program terminates, all of the live
+allocations will be dumped to the log. If the backtrace option was enabled,
+then the log will include the backtrace of the leaked allocations. This
+option is not useful when enabled globally because a lot of programs do not
+free everything before the program terminates.
+
+This option adds a special header to all allocations that contains
+information about the original allocation.
+
+Example leak error found in the log:

+</pre>
+
+This indicates that code is attempting to free an already freed pointer. The
+name in parenthesis indicates that the application called the function
+<i>free</i> with the bad pointer.
+
+For example, this message:
+

+</pre>
+
+This indicates that a function (malloc\_usable\_size) was called with
+a pointer that is either not allocated memory, or that the memory of
+the pointer has been corrupted.
+
+As with the other error message, the function in parenthesis is the
+function that was called with the bad pointer.
+
+Examples
+========
+Enable backtrace tracking of all allocation for all processes:
+
+<pre>
+  adb shell stop
+  adb shell setprop libc.debug.malloc.options backtrace
+  adb shell start
+</pre>
+
+Enable backtrace tracking for a specific process (ls):
+
+<pre>
+  adb shell setprop libc.debug.malloc.options backtrace
+  adb shell setprop libc.debug.malloc.program ls
+  adb shell ls
+</pre>
+
+Enable backtrace tracking for the zygote and zygote based processes:
+
+<pre>
+  adb shell stop
+  adb shell setprop libc.debug.malloc.program app_process
+  adb shell setprop libc.debug.malloc.options backtrace
+  adb shell start
+</pre>
+
+Enable multiple options (backtrace and guards):
+
+<pre>
+  adb shell stop
+  adb shell setprop libc.debug.malloc.options "\"backtrace guards\""
+  adb shell start
+</pre>
+
+Enable malloc debug when multiple processes have the same name. This method
+can be used to enable malloc debug for only a very specific process if
+multiple processes have the same name.
+
+Note: The double quotes in the adb shell command are necessary. Otherwise,
+the setprop command will fail since the backtrace guards options will look
+like two arguments instead of one.
+
+<pre>
+  adb shell
+  # setprop libc.debug.malloc.env_enabled
+  # setprop libc.debug.malloc.options backtrace
+  # export LIBC_DEBUG_MALLOC_ENABLE 1
+  # ls
+</pre>

+Native Memory Tracking using libc Callbacks
+-------------------------------------------
+Malloc debug can be used to get information on all of the live allocations
+in a process. The libc library in Android exports two calls that can be
+used to gather this data from a process. This tracking can be enabled using
+either the backtrace option or the backtrace\_enabled\_on\_signal option.
+
+The function to gather the data:
+
+<pre>
+<b>
+extern "C" void get_malloc_leak_info(uint8_t** info, size_t* overall_size, size_t* info_size, size_t* total_memory, size_t* backtrace_size);
+</b>
+</pre>
+
+<i>info</i> is set to a buffer allocated by the call that contains all of
+the allocation information.
+<i>overall\_size</i> is set to the total size of the buffer returned. If this
+<i>info\_size</i>
+value is zero, then there are no allocation being tracked.
+<i>total\_memory</i> is set to the sum of all allocation sizes that are live at
+the point of the function call. This does not include the memory allocated
+by the malloc debug library itself.
+<i>backtrace\_size</i> is set to the maximum number of backtrace entries
+that are present for each allocation.
+
+In order to free the buffer allocated by the function, call:
+
+<pre>
+<b>
+extern "C" void free_malloc_leak_info(uint8_t* info);
+</b>
+</pre>
+
+### Format of info Buffer
+<pre>
+size_t size_of_original_allocation
+size_t num_backtrace_frames
+uintptr_t pc1
+uintptr_t pc2
+uintptr_t pc3
+.
+.
+.
+</pre>
+
+The number of <i>uintptr\_t</i> values is determined by the value
+<i>backtrace\_size</i> as returned by the original call to
+<i>get\_malloc\_leak\_info</i>. This value is not variable, it is the same
+for all the returned data. The value
+<i>num\_backtrace\_frames</i> contains the real number of frames found. The
+extra frames are set to zero. Each <i>uintptr\_t</i> is a pc of the callstack.
+The calls from within the malloc debug library are automatically removed.
+
+For 32 bit systems, <i>size\_t</i> and <i>uintptr\_t</i> are both 4 byte values.
+
+For 64 bit systems, <i>size\_t</i> and <i>uintptr\_t</i> are both 8 byte values.
+
+The total number of these structures returned in <i>info</i> is
+<i>overall\_size</i> divided by <i>info\_size</i>.
+
+Note, the size value in each allocation data structure will have bit 31 set
+if this allocation was created by the Zygote process. This helps to distinguish
+between native allocations created by the application.

-/*
-  This is a version (aka dlmalloc) of malloc/free/realloc written by
-  Doug Lea and released to the public domain, as explained at
-  http://creativecommons.org/publicdomain/zero/1.0/ Send questions,
-  comments, complaints, performance data, etc to dl@cs.oswego.edu
-
-* Version 2.8.6 Wed Aug 29 06:57:58 2012  Doug Lea
-   Note: There may be an updated version of this malloc obtainable at
-           ftp://gee.cs.oswego.edu/pub/misc/malloc.c
-         Check before installing!
-
-* Quickstart
-
-  This library is all in one file to simplify the most common usage:
-  ftp it, compile it (-O3), and link it into another program. All of
-  the compile-time options default to reasonable values for use on
-  most platforms.  You might later want to step through various
-  compile-time and dynamic tuning options.
-
-  For convenience, an include file for code using this malloc is at:
-     ftp://gee.cs.oswego.edu/pub/misc/malloc-2.8.6.h
-  You don't really need this .h file unless you call functions not
-  defined in your system include files.  The .h file contains only the
-  excerpts from this file needed for using this malloc on ANSI C/C++
-  systems, so long as you haven't changed compile-time options about
-  naming and tuning parameters.  If you do, then you can create your
-  own malloc.h that does include all settings by cutting at the point
-  indicated below. Note that you may already by default be using a C
-  library containing a malloc that is based on some version of this
-  malloc (for example in linux). You might still want to use the one
-  in this file to customize settings or to avoid overheads associated
-  with library versions.
-
-* Vital statistics:
-
-  Supported pointer/size_t representation:       4 or 8 bytes
-       size_t MUST be an unsigned type of the same width as
-       pointers. (If you are using an ancient system that declares
-       size_t as a signed type, or need it to be a different width
-       than pointers, you can use a previous release of this malloc
-       (e.g. 2.7.2) supporting these.)
-
-  Alignment:                                     8 bytes (minimum)
-       This suffices for nearly all current machines and C compilers.
-       However, you can define MALLOC_ALIGNMENT to be wider than this
-       if necessary (up to 128bytes), at the expense of using more space.
-
-  Minimum overhead per allocated chunk:   4 or  8 bytes (if 4byte sizes)
-                                          8 or 16 bytes (if 8byte sizes)
-       Each malloced chunk has a hidden word of overhead holding size
-       and status information, and additional cross-check word
-       if FOOTERS is defined.
-
-  Minimum allocated size: 4-byte ptrs:  16 bytes    (including overhead)
-                          8-byte ptrs:  32 bytes    (including overhead)
-
-       Even a request for zero bytes (i.e., malloc(0)) returns a
-       pointer to something of the minimum allocatable size.
-       The maximum overhead wastage (i.e., number of extra bytes
-       allocated than were requested in malloc) is less than or equal
-       to the minimum size, except for requests >= mmap_threshold that
-       are serviced via mmap(), where the worst case wastage is about
-       32 bytes plus the remainder from a system page (the minimal
-       mmap unit); typically 4096 or 8192 bytes.
-
-  Security: static-safe; optionally more or less
-       The "security" of malloc refers to the ability of malicious
-       code to accentuate the effects of errors (for example, freeing
-       space that is not currently malloc'ed or overwriting past the
-       ends of chunks) in code that calls malloc.  This malloc
-       guarantees not to modify any memory locations below the base of
-       heap, i.e., static variables, even in the presence of usage
-       errors.  The routines additionally detect most improper frees
-       and reallocs.  All this holds as long as the static bookkeeping
-       for malloc itself is not corrupted by some other means.  This
-       is only one aspect of security -- these checks do not, and
-       cannot, detect all possible programming errors.
-
-       If FOOTERS is defined nonzero, then each allocated chunk
-       carries an additional check word to verify that it was malloced
-       from its space.  These check words are the same within each
-       execution of a program using malloc, but differ across
-       executions, so externally crafted fake chunks cannot be
-       freed. This improves security by rejecting frees/reallocs that
-       could corrupt heap memory, in addition to the checks preventing
-       writes to statics that are always on.  This may further improve
-       security at the expense of time and space overhead.  (Note that
-       FOOTERS may also be worth using with MSPACES.)
-
-       By default detected errors cause the program to abort (calling
-       "abort()"). You can override this to instead proceed past
-       errors by defining PROCEED_ON_ERROR.  In this case, a bad free
-       has no effect, and a malloc that encounters a bad address
-       caused by user overwrites will ignore the bad address by
-       dropping pointers and indices to all known memory. This may
-       be appropriate for programs that should continue if at all
-       possible in the face of programming errors, although they may
-       run out of memory because dropped memory is never reclaimed.
-
-       If you don't like either of these options, you can define
-       CORRUPTION_ERROR_ACTION and USAGE_ERROR_ACTION to do anything
-       else. And if if you are sure that your program using malloc has
-       no errors or vulnerabilities, you can define INSECURE to 1,
-       which might (or might not) provide a small performance improvement.
-
-       It is also possible to limit the maximum total allocatable
-       space, using malloc_set_footprint_limit. This is not
-       designed as a security feature in itself (calls to set limits
-       are not screened or privileged), but may be useful as one
-       aspect of a secure implementation.
-
-  Thread-safety: NOT thread-safe unless USE_LOCKS defined non-zero
-       When USE_LOCKS is defined, each public call to malloc, free,
-       etc is surrounded with a lock. By default, this uses a plain
-       pthread mutex, win32 critical section, or a spin-lock if if
-       available for the platform and not disabled by setting
-       USE_SPIN_LOCKS=0.  However, if USE_RECURSIVE_LOCKS is defined,
-       recursive versions are used instead (which are not required for
-       base functionality but may be needed in layered extensions).
-       Using a global lock is not especially fast, and can be a major
-       bottleneck.  It is designed only to provide minimal protection
-       in concurrent environments, and to provide a basis for
-       extensions.  If you are using malloc in a concurrent program,
-       consider instead using nedmalloc
-       (http://www.nedprod.com/programs/portable/nedmalloc/) or
-       ptmalloc (See http://www.malloc.de), which are derived from
-       versions of this malloc.
-
-  System requirements: Any combination of MORECORE and/or MMAP/MUNMAP
-       This malloc can use unix sbrk or any emulation (invoked using
-       the CALL_MORECORE macro) and/or mmap/munmap or any emulation
-       (invoked using CALL_MMAP/CALL_MUNMAP) to get and release system
-       memory.  On most unix systems, it tends to work best if both
-       MORECORE and MMAP are enabled.  On Win32, it uses emulations
-       based on VirtualAlloc. It also uses common C library functions
-       like memset.
-
-  Compliance: I believe it is compliant with the Single Unix Specification
-       (See http://www.unix.org). Also SVID/XPG, ANSI C, and probably
-       others as well.
-
-* Overview of algorithms
-
-  This is not the fastest, most space-conserving, most portable, or
-  most tunable malloc ever written. However it is among the fastest
-  while also being among the most space-conserving, portable and
-  tunable.  Consistent balance across these factors results in a good
-  general-purpose allocator for malloc-intensive programs.
-
-  In most ways, this malloc is a best-fit allocator. Generally, it
-  chooses the best-fitting existing chunk for a request, with ties
-  broken in approximately least-recently-used order. (This strategy
-  normally maintains low fragmentation.) However, for requests less
-  than 256bytes, it deviates from best-fit when there is not an
-  exactly fitting available chunk by preferring to use space adjacent
-  to that used for the previous small request, as well as by breaking
-  ties in approximately most-recently-used order. (These enhance
-  locality of series of small allocations.)  And for very large requests
-  (>= 256Kb by default), it relies on system memory mapping
-  facilities, if supported.  (This helps avoid carrying around and
-  possibly fragmenting memory used only for large chunks.)
-
-  All operations (except malloc_stats and mallinfo) have execution
-  times that are bounded by a constant factor of the number of bits in
-  a size_t, not counting any clearing in calloc or copying in realloc,
-  or actions surrounding MORECORE and MMAP that have times
-  proportional to the number of non-contiguous regions returned by
-  system allocation routines, which is often just 1. In real-time
-  applications, you can optionally suppress segment traversals using
-  NO_SEGMENT_TRAVERSAL, which assures bounded execution even when
-  system allocators return non-contiguous spaces, at the typical
-  expense of carrying around more memory and increased fragmentation.
-
-  The implementation is not very modular and seriously overuses
-  macros. Perhaps someday all C compilers will do as good a job
-  inlining modular code as can now be done by brute-force expansion,
-  but now, enough of them seem not to.
-
-  Some compilers issue a lot of warnings about code that is
-  dead/unreachable only on some platforms, and also about intentional
-  uses of negation on unsigned types. All known cases of each can be
-  ignored.
-
-  For a longer but out of date high-level description, see
-     http://gee.cs.oswego.edu/dl/html/malloc.html
-
-* MSPACES
-  If MSPACES is defined, then in addition to malloc, free, etc.,
-  this file also defines mspace_malloc, mspace_free, etc. These
-  are versions of malloc routines that take an "mspace" argument
-  obtained using create_mspace, to control all internal bookkeeping.
-  If ONLY_MSPACES is defined, only these versions are compiled.
-  So if you would like to use this allocator for only some allocations,
-  and your system malloc for others, you can compile with
-  ONLY_MSPACES and then do something like...
-    static mspace mymspace = create_mspace(0,0); // for example
-    #define mymalloc(bytes)  mspace_malloc(mymspace, bytes)
-
-  (Note: If you only need one instance of an mspace, you can instead
-  use "USE_DL_PREFIX" to relabel the global malloc.)
-
-  You can similarly create thread-local allocators by storing
-  mspaces as thread-locals. For example:
-    static __thread mspace tlms = 0;
-    void*  tlmalloc(size_t bytes) {
-      if (tlms == 0) tlms = create_mspace(0, 0);
-      return mspace_malloc(tlms, bytes);
-    }
-    void  tlfree(void* mem) { mspace_free(tlms, mem); }
-
-  Unless FOOTERS is defined, each mspace is completely independent.
-  You cannot allocate from one and free to another (although
-  conformance is only weakly checked, so usage errors are not always
-  caught). If FOOTERS is defined, then each chunk carries around a tag
-  indicating its originating mspace, and frees are directed to their
-  originating spaces. Normally, this requires use of locks.
-
- -------------------------  Compile-time options ---------------------------
-
-Be careful in setting #define values for numerical constants of type
-size_t. On some systems, literal values are not automatically extended
-to size_t precision unless they are explicitly casted. You can also
-use the symbolic values MAX_SIZE_T, SIZE_T_ONE, etc below.
-
-WIN32                    default: defined if _WIN32 defined
-  Defining WIN32 sets up defaults for MS environment and compilers.
-  Otherwise defaults are for unix. Beware that there seem to be some
-  cases where this malloc might not be a pure drop-in replacement for
-  Win32 malloc: Random-looking failures from Win32 GDI API's (eg;
-  SetDIBits()) may be due to bugs in some video driver implementations
-  when pixel buffers are malloc()ed, and the region spans more than
-  one VirtualAlloc()ed region. Because dlmalloc uses a small (64Kb)
-  default granularity, pixel buffers may straddle virtual allocation
-  regions more often than when using the Microsoft allocator.  You can
-  avoid this by using VirtualAlloc() and VirtualFree() for all pixel
-  buffers rather than using malloc().  If this is not possible,
-  recompile this malloc with a larger DEFAULT_GRANULARITY. Note:
-  in cases where MSC and gcc (cygwin) are known to differ on WIN32,
-  conditions use _MSC_VER to distinguish them.
-
-DLMALLOC_EXPORT       default: extern
-  Defines how public APIs are declared. If you want to export via a
-  Windows DLL, you might define this as
-    #define DLMALLOC_EXPORT extern  __declspec(dllexport)
-  If you want a POSIX ELF shared object, you might use
-    #define DLMALLOC_EXPORT extern __attribute__((visibility("default")))
-
-MALLOC_ALIGNMENT         default: (size_t)(2 * sizeof(void *))
-  Controls the minimum alignment for malloc'ed chunks.  It must be a
-  power of two and at least 8, even on machines for which smaller
-  alignments would suffice. It may be defined as larger than this
-  though. Note however that code and data structures are optimized for
-  the case of 8-byte alignment.
-
-MSPACES                  default: 0 (false)
-  If true, compile in support for independent allocation spaces.
-  This is only supported if HAVE_MMAP is true.
-
-ONLY_MSPACES             default: 0 (false)
-  If true, only compile in mspace versions, not regular versions.
-
-USE_LOCKS                default: 0 (false)
-  Causes each call to each public routine to be surrounded with
-  pthread or WIN32 mutex lock/unlock. (If set true, this can be
-  overridden on a per-mspace basis for mspace versions.) If set to a
-  non-zero value other than 1, locks are used, but their
-  implementation is left out, so lock functions must be supplied manually,
-  as described below.
-
-USE_SPIN_LOCKS           default: 1 iff USE_LOCKS and spin locks available
-  If true, uses custom spin locks for locking. This is currently
-  supported only gcc >= 4.1, older gccs on x86 platforms, and recent
-  MS compilers.  Otherwise, posix locks or win32 critical sections are
-  used.
-
-USE_RECURSIVE_LOCKS      default: not defined
-  If defined nonzero, uses recursive (aka reentrant) locks, otherwise
-  uses plain mutexes. This is not required for malloc proper, but may
-  be needed for layered allocators such as nedmalloc.
-
-LOCK_AT_FORK            default: not defined
-  If defined nonzero, performs pthread_atfork upon initialization
-  to initialize child lock while holding parent lock. The implementation
-  assumes that pthread locks (not custom locks) are being used. In other
-  cases, you may need to customize the implementation.
-
-FOOTERS                  default: 0
-  If true, provide extra checking and dispatching by placing
-  information in the footers of allocated chunks. This adds
-  space and time overhead.
-
-INSECURE                 default: 0
-  If true, omit checks for usage errors and heap space overwrites.
-
-USE_DL_PREFIX            default: NOT defined
-  Causes compiler to prefix all public routines with the string 'dl'.
-  This can be useful when you only want to use this malloc in one part
-  of a program, using your regular system malloc elsewhere.
-
-MALLOC_INSPECT_ALL       default: NOT defined
-  If defined, compiles malloc_inspect_all and mspace_inspect_all, that
-  perform traversal of all heap space.  Unless access to these
-  functions is otherwise restricted, you probably do not want to
-  include them in secure implementations.
-
-ABORT                    default: defined as abort()
-  Defines how to abort on failed checks.  On most systems, a failed
-  check cannot die with an "assert" or even print an informative
-  message, because the underlying print routines in turn call malloc,
-  which will fail again.  Generally, the best policy is to simply call
-  abort(). It's not very useful to do more than this because many
-  errors due to overwriting will show up as address faults (null, odd
-  addresses etc) rather than malloc-triggered checks, so will also
-  abort.  Also, most compilers know that abort() does not return, so
-  can better optimize code conditionally calling it.
-
-PROCEED_ON_ERROR           default: defined as 0 (false)
-  Controls whether detected bad addresses cause them to bypassed
-  rather than aborting. If set, detected bad arguments to free and
-  realloc are ignored. And all bookkeeping information is zeroed out
-  upon a detected overwrite of freed heap space, thus losing the
-  ability to ever return it from malloc again, but enabling the
-  application to proceed. If PROCEED_ON_ERROR is defined, the
-  static variable malloc_corruption_error_count is compiled in
-  and can be examined to see if errors have occurred. This option
-  generates slower code than the default abort policy.
-
-DEBUG                    default: NOT defined
-  The DEBUG setting is mainly intended for people trying to modify
-  this code or diagnose problems when porting to new platforms.
-  However, it may also be able to better isolate user errors than just
-  using runtime checks.  The assertions in the check routines spell
-  out in more detail the assumptions and invariants underlying the
-  algorithms.  The checking is fairly extensive, and will slow down
-  execution noticeably. Calling malloc_stats or mallinfo with DEBUG
-  set will attempt to check every non-mmapped allocated and free chunk
-  in the course of computing the summaries.
-
-ABORT_ON_ASSERT_FAILURE   default: defined as 1 (true)
-  Debugging assertion failures can be nearly impossible if your
-  version of the assert macro causes malloc to be called, which will
-  lead to a cascade of further failures, blowing the runtime stack.
-  ABORT_ON_ASSERT_FAILURE cause assertions failures to call abort(),
-  which will usually make debugging easier.
-
-MALLOC_FAILURE_ACTION     default: sets errno to ENOMEM, or no-op on win32
-  The action to take before "return 0" when malloc fails to be able to
-  return memory because there is none available.
-
-HAVE_MORECORE             default: 1 (true) unless win32 or ONLY_MSPACES
-  True if this system supports sbrk or an emulation of it.
-
-MORECORE                  default: sbrk
-  The name of the sbrk-style system routine to call to obtain more
-  memory.  See below for guidance on writing custom MORECORE
-  functions. The type of the argument to sbrk/MORECORE varies across
-  systems.  It cannot be size_t, because it supports negative
-  arguments, so it is normally the signed type of the same width as
-  size_t (sometimes declared as "intptr_t").  It doesn't much matter
-  though. Internally, we only call it with arguments less than half
-  the max value of a size_t, which should work across all reasonable
-  possibilities, although sometimes generating compiler warnings.
-
-MORECORE_CONTIGUOUS       default: 1 (true) if HAVE_MORECORE
-  If true, take advantage of fact that consecutive calls to MORECORE
-  with positive arguments always return contiguous increasing
-  addresses.  This is true of unix sbrk. It does not hurt too much to
-  set it true anyway, since malloc copes with non-contiguities.
-  Setting it false when definitely non-contiguous saves time
-  and possibly wasted space it would take to discover this though.
-
-MORECORE_CANNOT_TRIM      default: NOT defined
-  True if MORECORE cannot release space back to the system when given
-  negative arguments. This is generally necessary only if you are
-  using a hand-crafted MORECORE function that cannot handle negative
-  arguments.
-
-NO_SEGMENT_TRAVERSAL       default: 0
-  If non-zero, suppresses traversals of memory segments
-  returned by either MORECORE or CALL_MMAP. This disables
-  merging of segments that are contiguous, and selectively
-  releasing them to the OS if unused, but bounds execution times.
-
-HAVE_MMAP                 default: 1 (true)
-  True if this system supports mmap or an emulation of it.  If so, and
-  HAVE_MORECORE is not true, MMAP is used for all system
-  allocation. If set and HAVE_MORECORE is true as well, MMAP is
-  primarily used to directly allocate very large blocks. It is also
-  used as a backup strategy in cases where MORECORE fails to provide
-  space from system. Note: A single call to MUNMAP is assumed to be
-  able to unmap memory that may have be allocated using multiple calls
-  to MMAP, so long as they are adjacent.
-
-HAVE_MREMAP               default: 1 on linux, else 0
-  If true realloc() uses mremap() to re-allocate large blocks and
-  extend or shrink allocation spaces.
-
-MMAP_CLEARS               default: 1 except on WINCE.
-  True if mmap clears memory so calloc doesn't need to. This is true
-  for standard unix mmap using /dev/zero and on WIN32 except for WINCE.
-
-USE_BUILTIN_FFS            default: 0 (i.e., not used)
-  Causes malloc to use the builtin ffs() function to compute indices.
-  Some compilers may recognize and intrinsify ffs to be faster than the
-  supplied C version. Also, the case of x86 using gcc is special-cased
-  to an asm instruction, so is already as fast as it can be, and so
-  this setting has no effect. Similarly for Win32 under recent MS compilers.
-  (On most x86s, the asm version is only slightly faster than the C version.)
-
-malloc_getpagesize         default: derive from system includes, or 4096.
-  The system page size. To the extent possible, this malloc manages
-  memory from the system in page-size units.  This may be (and
-  usually is) a function rather than a constant. This is ignored
-  if WIN32, where page size is determined using getSystemInfo during
-  initialization.
-
-USE_DEV_RANDOM             default: 0 (i.e., not used)
-  Causes malloc to use /dev/random to initialize secure magic seed for
-  stamping footers. Otherwise, the current time is used.
-
-NO_MALLINFO                default: 0
-  If defined, don't compile "mallinfo". This can be a simple way
-  of dealing with mismatches between system declarations and
-  those in this file.
-
-MALLINFO_FIELD_TYPE        default: size_t
-  The type of the fields in the mallinfo struct. This was originally
-  defined as "int" in SVID etc, but is more usefully defined as
-  size_t. The value is used only if  HAVE_USR_INCLUDE_MALLOC_H is not set
-
-NO_MALLOC_STATS            default: 0
-  If defined, don't compile "malloc_stats". This avoids calls to
-  fprintf and bringing in stdio dependencies you might not want.
-
-REALLOC_ZERO_BYTES_FREES    default: not defined
-  This should be set if a call to realloc with zero bytes should
-  be the same as a call to free. Some people think it should. Otherwise,
-  since this malloc returns a unique pointer for malloc(0), so does
-  realloc(p, 0).
-
-LACKS_UNISTD_H, LACKS_FCNTL_H, LACKS_SYS_PARAM_H, LACKS_SYS_MMAN_H
-LACKS_STRINGS_H, LACKS_STRING_H, LACKS_SYS_TYPES_H,  LACKS_ERRNO_H
-LACKS_STDLIB_H LACKS_SCHED_H LACKS_TIME_H  default: NOT defined unless on WIN32
-  Define these if your system does not have these header files.
-  You might need to manually insert some of the declarations they provide.
-
-DEFAULT_GRANULARITY        default: page size if MORECORE_CONTIGUOUS,
-                                system_info.dwAllocationGranularity in WIN32,
-                                otherwise 64K.
-      Also settable using mallopt(M_GRANULARITY, x)
-  The unit for allocating and deallocating memory from the system.  On
-  most systems with contiguous MORECORE, there is no reason to
-  make this more than a page. However, systems with MMAP tend to
-  either require or encourage larger granularities.  You can increase
-  this value to prevent system allocation functions to be called so
-  often, especially if they are slow.  The value must be at least one
-  page and must be a power of two.  Setting to 0 causes initialization
-  to either page size or win32 region size.  (Note: In previous
-  versions of malloc, the equivalent of this option was called
-  "TOP_PAD")
-
-DEFAULT_TRIM_THRESHOLD    default: 2MB
-      Also settable using mallopt(M_TRIM_THRESHOLD, x)
-  The maximum amount of unused top-most memory to keep before
-  releasing via malloc_trim in free().  Automatic trimming is mainly
-  useful in long-lived programs using contiguous MORECORE.  Because
-  trimming via sbrk can be slow on some systems, and can sometimes be
-  wasteful (in cases where programs immediately afterward allocate
-  more large chunks) the value should be high enough so that your
-  overall system performance would improve by releasing this much
-  memory.  As a rough guide, you might set to a value close to the
-  average size of a process (program) running on your system.
-  Releasing this much memory would allow such a process to run in
-  memory.  Generally, it is worth tuning trim thresholds when a
-  program undergoes phases where several large chunks are allocated
-  and released in ways that can reuse each other's storage, perhaps
-  mixed with phases where there are no such chunks at all. The trim
-  value must be greater than page size to have any useful effect.  To
-  disable trimming completely, you can set to MAX_SIZE_T. Note that the trick
-  some people use of mallocing a huge space and then freeing it at
-  program startup, in an attempt to reserve system memory, doesn't
-  have the intended effect under automatic trimming, since that memory
-  will immediately be returned to the system.
-
-DEFAULT_MMAP_THRESHOLD       default: 256K
-      Also settable using mallopt(M_MMAP_THRESHOLD, x)
-  The request size threshold for using MMAP to directly service a
-  request. Requests of at least this size that cannot be allocated
-  using already-existing space will be serviced via mmap.  (If enough
-  normal freed space already exists it is used instead.)  Using mmap
-  segregates relatively large chunks of memory so that they can be
-  individually obtained and released from the host system. A request
-  serviced through mmap is never reused by any other request (at least
-  not directly; the system may just so happen to remap successive
-  requests to the same locations).  Segregating space in this way has
-  the benefits that: Mmapped space can always be individually released
-  back to the system, which helps keep the system level memory demands
-  of a long-lived program low.  Also, mapped memory doesn't become
-  `locked' between other chunks, as can happen with normally allocated
-  chunks, which means that even trimming via malloc_trim would not
-  release them.  However, it has the disadvantage that the space
-  cannot be reclaimed, consolidated, and then used to service later
-  requests, as happens with normal chunks.  The advantages of mmap
-  nearly always outweigh disadvantages for "large" chunks, but the
-  value of "large" may vary across systems.  The default is an
-  empirically derived value that works well in most systems. You can
-  disable mmap by setting to MAX_SIZE_T.
-
-MAX_RELEASE_CHECK_RATE   default: 4095 unless not HAVE_MMAP
-  The number of consolidated frees between checks to release
-  unused segments when freeing. When using non-contiguous segments,
-  especially with multiple mspaces, checking only for topmost space
-  doesn't always suffice to trigger trimming. To compensate for this,
-  free() will, with a period of MAX_RELEASE_CHECK_RATE (or the
-  current number of segments, if greater) try to release unused
-  segments to the OS when freeing chunks that result in
-  consolidation. The best value for this parameter is a compromise
-  between slowing down frees with relatively costly checks that
-  rarely trigger versus holding on to unused memory. To effectively
-  disable, set to MAX_SIZE_T. This may lead to a very slight speed
-  improvement at the expense of carrying around more memory.

-  must be of at least n_elements in length. It is filled in with the
-  pointers to the chunks.
-
-  In either case, independent_comalloc returns this pointer array, or
-  null if the allocation failed.  If n_elements is zero and chunks is
-  null, it returns a chunk representing an array with zero elements
-  (which should be freed if not wanted).
-
-  Each element must be freed when it is no longer needed. This can be
-  done all at once using bulk_free.
-
-  independent_comallac differs from independent_calloc in that each
-  element may have a different size, and also that it does not
-  automatically clear elements.
-
-  independent_comalloc can be used to speed up allocation in cases
-  where several structs or objects must always be allocated at the
-  same time.  For example:
-
-  struct Head { ... }
-  struct Foot { ... }
-
-  void send_message(char* msg) {
-    int msglen = strlen(msg);
-    size_t sizes[3] = { sizeof(struct Head), msglen, sizeof(struct Foot) };
-    void* chunks[3];
-    if (independent_comalloc(3, sizes, chunks) == 0)
-      die();
-    struct Head* head = (struct Head*)(chunks[0]);
-    char*        body = (char*)(chunks[1]);
-    struct Foot* foot = (struct Foot*)(chunks[2]);
-    // ...
-  }
-
-  In general though, independent_comalloc is worth using only for
-  larger values of n_elements. For small values, you probably won't
-  detect enough difference from series of malloc calls to bother.
-
-  Overuse of independent_comalloc can increase overall memory usage,
-  since it cannot reuse existing noncontiguous small chunks that
-  might be available for some of the elements.

-/*
-  When locks are defined, there is one global lock, plus
-  one per-mspace lock.
-
-  The global lock_ensures that mparams.magic and other unique
-  mparams values are initialized only once. It also protects
-  sequences of calls to MORECORE.  In many cases sys_alloc requires
-  two calls, that should not be interleaved with calls by other
-  threads.  This does not protect against direct calls to MORECORE
-  by other threads not using this lock, so there is still code to
-  cope the best we can on interference.
-
-  Per-mspace locks surround calls to malloc, free, etc.
-  By default, locks are simple non-reentrant mutexes.
-
-  Because lock-protected regions generally have bounded times, it is
-  OK to use the supplied simple spinlocks. Spinlocks are likely to
-  improve performance for lightly contended applications, but worsen
-  performance under heavy contention.
-
-  If USE_LOCKS is > 1, the definitions of lock routines here are
-  bypassed, in which case you will need to define the type MLOCK_T,
-  and at least INITIAL_LOCK, DESTROY_LOCK, ACQUIRE_LOCK, RELEASE_LOCK
-  and TRY_LOCK.  You must also declare a
-    static MLOCK_T malloc_global_mutex = { initialization values };.

-/*
-  (The following includes lightly edited explanations by Colin Plumb.)
-
-  The malloc_chunk declaration below is misleading (but accurate and
-  necessary).  It declares a "view" into memory allowing access to
-  necessary fields at known offsets from a given base.
-
-  Chunks of memory are maintained using a `boundary tag' method as
-  originally described by Knuth.  (See the paper by Paul Wilson
-  ftp://ftp.cs.utexas.edu/pub/garbage/allocsrv.ps for a survey of such
-  techniques.)  Sizes of free chunks are stored both in the front of
-  each chunk and at the end.  This makes consolidating fragmented
-  chunks into bigger chunks fast.  The head fields also hold bits
-  representing whether chunks are free or in use.
-
-  Here are some pictures to make it clearer.  They are "exploded" to
-  show that the state of a chunk can be thought of as extending from
-  the high 31 bits of the head field of its header through the
-  prev_foot and PINUSE_BIT bit of the following chunk header.
-
-  A chunk that's in use looks like:
-
-   chunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
-           | Size of previous chunk (if P = 0)                             |

-  Note that since we always merge adjacent free chunks, the chunks
-  adjacent to a free chunk must be in use.
-
-  Given a pointer to a chunk (which can be derived trivially from the
-  payload pointer) we can, in O(1) time, find out whether the adjacent
-  chunks are free, and if so, unlink them from the lists that they
-  are on and merge them with the current chunk.
-
-  Chunks always begin on even word boundaries, so the mem portion
-  (which is returned to the user) is also on an even word boundary, and
-  thus at least double-word aligned.
-
-  The P (PINUSE_BIT) bit, stored in the unused low-order bit of the
-  chunk size (which is always a multiple of two words), is an in-use
-  bit for the *previous* chunk.  If that bit is *clear*, then the
-  word before the current chunk size contains the previous chunk
-  size, and can be used to find the front of the previous chunk.
-  The very first chunk allocated always has this bit set, preventing
-  access to non-existent (or non-owned) memory. If pinuse is set for
-  any given chunk, then you CANNOT determine the size of the
-  previous chunk, and might even get a memory addressing fault when
-  trying to do so.
-
-  The C (CINUSE_BIT) bit, stored in the unused second-lowest bit of
-  the chunk size redundantly records whether the current chunk is
-  inuse (unless the chunk is mmapped). This redundancy enables usage
-  checks within free and realloc, and reduces indirection when freeing
-  and consolidating chunks.
-
-  Each freshly allocated chunk must have both cinuse and pinuse set.
-  That is, each allocated chunk borders either a previously allocated
-  and still in-use chunk, or the base of its memory arena. This is
-  ensured by making all allocations from the `lowest' part of any
-  found chunk.  Further, no free chunk physically borders another one,
-  so each free chunk is known to be preceded and followed by either
-  inuse chunks or the ends of memory.
-
-  Note that the `foot' of the current chunk is actually represented
-  as the prev_foot of the NEXT chunk. This makes it easier to
-  deal with alignments etc but can be very confusing when trying
-  to extend or adapt this code.
-
-  The exceptions to all this are
-
-     1. The special chunk `top' is the top-most available chunk (i.e.,
-        the one bordering the end of available memory). It is treated
-        specially.  Top is never included in any bin, is used only if
-        no other chunk is available, and is released back to the
-        system if it is very large (see M_TRIM_THRESHOLD).  In effect,
-        the top chunk is treated as larger (and thus less well
-        fitting) than any other available chunk.  The top chunk
-        doesn't update its trailing size field since there is no next
-        contiguous chunk that would have to index off it. However,
-        space is still allocated for it (TOP_FOOT_SIZE) to enable
-        separation or merging when space is extended.

-
-  Each tree holding treenodes is a tree of unique chunk sizes.  Chunks
-  of the same size are arranged in a circularly-linked list, with only
-  the oldest chunk (the next to be used, in our FIFO ordering)
-  actually in the tree.  (Tree members are distinguished by a non-null
-  parent pointer.)  If a chunk with the same size an an existing node
-  is inserted, it is linked off the existing node using pointers that
-  work in the same way as fd/bk pointers of small chunks.
-
-  Each tree contains a power of 2 sized range of chunk sizes (the
-  smallest is 0x100 <= x < 0x180), which is is divided in half at each
-  tree level, with the chunks in the smaller half of the range (0x100
-  <= x < 0x140 for the top nose) in the left subtree and the larger
-  half (0x140 <= x < 0x180) in the right subtree.  This is, of course,
-  done by inspecting individual bits.
-
-  Using these rules, each node's left subtree contains all smaller
-  sizes than its right subtree.  However, the node at the root of each
-  subtree has no particular ordering relationship to either.  (The
-  dividing line between the subtree sizes is based on trie relation.)
-  If we remove the last chunk of a given size from the interior of the
-  tree, we need to replace it with a leaf node.  The tree ordering
-  rules permit a node to be replaced by any leaf below it.
-
-  The smallest chunk in a tree (a common operation in a best-fit
-  allocator) can be found by walking a path to the leftmost leaf in
-  the tree.  Unlike a usual binary tree, where we follow left child
-  pointers until we reach a null, here we follow the right child
-  pointer any time the left one is null, until we reach a leaf with
-  both child pointers null. The smallest chunk in the tree will be
-  somewhere along that path.
-
-  The worst case number of steps to add, find, or remove a node is
-  bounded by the number of bits differentiating chunks within
-  bins. Under current bin calculations, this ranges from 6 up to 21
-  (for 32 bit sizes) or up to 53 (for 64 bit sizes). The typical case
-  is of course much better.

-/* ----------------------------- Segments -------------------------------- */
-
-/*
-  Each malloc space may include non-contiguous segments, held in a
-  list headed by an embedded malloc_segment record representing the
-  top-most space. Segments also include flags holding properties of
-  the space. Large chunks that are directly allocated by mmap are not
-  included in this list. They are instead independently created and
-  destroyed without otherwise keeping track of them.
-
-  Segment management mainly comes into play for spaces allocated by
-  MMAP.  Any call to MMAP might or might not return memory that is
-  adjacent to an existing segment.  MORECORE normally contiguously
-  extends the current space, so this space is almost always adjacent,
-  which is simpler and faster to deal with. (This is why MORECORE is
-  used preferentially to MMAP when both are available -- see
-  sys_alloc.)  When allocating using MMAP, we don't use any of the
-  hinting mechanisms (inconsistently) supported in various
-  implementations of unix mmap, or distinguish reserving from
-  committing memory. Instead, we just ask for space, and exploit
-  contiguity when we get it.  It is probably possible to do
-  better than this on some systems, but no general scheme seems
-  to be significantly better.
-
-  Management entails a simpler variant of the consolidation scheme
-  used for chunks to reduce fragmentation -- new adjacent memory is
-  normally prepended or appended to an existing segment. However,
-  there are limitations compared to chunk consolidation that mostly
-  reflect the fact that segment processing is relatively infrequent
-  (occurring only when getting memory from system) and that we
-  don't expect to have huge numbers of segments:
-
-  * Segments are not indexed, so traversal requires linear scans.  (It
-    would be possible to index these, but is not worth the extra
-    overhead and complexity for most programs on most platforms.)
-  * New segments are only appended to old ones when holding top-most
-    memory; if they cannot be prepended to others, they are held in
-    different segments.
-
-  Except for the top-most segment of an mstate, each segment record
-  is kept at the tail of its segment. Segments are added by pushing
-  segment records onto the list headed by &mstate.seg for the
-  containing mstate.
-
-  Segment flags control allocation/merge/deallocation policies:
-  * If EXTERN_BIT set, then we did not allocate this segment,
-    and so should not try to deallocate or merge with others.
-    (This currently holds only for the initial segment passed
-    into create_mspace_with_base.)
-  * If USE_MMAP_BIT set, the segment may be merged with
-    other surrounding mmapped segments and trimmed/de-allocated
-    using munmap.
-  * If neither bit is set, then the segment was obtained using
-    MORECORE so can be merged with surrounding MORECORE'd segments
-    and deallocated/trimmed using MORECORE with negative arguments.

-/* ---------------------------- malloc_state ----------------------------- */
-
-/*
-   A malloc_state holds all of the bookkeeping for a space.
-   The main fields are:
-
-  Top
-    The topmost chunk of the currently active segment. Its size is
-    cached in topsize.  The actual size of topmost space is
-    topsize+TOP_FOOT_SIZE, which includes space reserved for adding
-    fenceposts and segment records if necessary when getting more
-    space from the system.  The size at which to autotrim top is
-    cached from mparams in trim_check, except that it is disabled if
-    an autotrim fails.
-
-  Designated victim (dv)
-    This is the preferred chunk for servicing small requests that
-    don't have exact fits.  It is normally the chunk split off most
-    recently to service another small request.  Its size is cached in
-    dvsize. The link fields of this chunk are not maintained since it
-    is not kept in a bin.
-
-  SmallBins
-    An array of bin headers for free chunks.  These bins hold chunks
-    with sizes less than MIN_LARGE_SIZE bytes. Each bin contains
-    chunks of all the same size, spaced 8 bytes apart.  To simplify
-    use in double-linked lists, each bin header acts as a malloc_chunk
-    pointing to the real first node, if it exists (else pointing to
-    itself).  This avoids special-casing for headers.  But to avoid
-    waste, we allocate only the fd/bk pointers of bins, and then use
-    repositioning tricks to treat these as the fields of a chunk.
-
-  TreeBins
-    Treebins are pointers to the roots of trees holding a range of
-    sizes. There are 2 equally spaced treebins for each power of two
-    from TREE_SHIFT to TREE_SHIFT+16. The last bin holds anything
-    larger.
-
-  Bin maps
-    There is one bit map for small bins ("smallmap") and one for
-    treebins ("treemap).  Each bin sets its bit when non-empty, and
-    clears the bit when empty.  Bit operations are then used to avoid
-    bin-by-bin searching -- nearly all "search" is done without ever
-    looking at bins that won't be selected.  The bit maps
-    conservatively use 32 bits per map word, even if on 64bit system.
-    For a good description of some of the bit-based techniques used
-    here, see Henry S. Warren Jr's book "Hacker's Delight" (and
-    supplement at http://hackersdelight.org/). Many of these are
-    intended to reduce the branchiness of paths through malloc etc, as
-    well as to reduce the number of memory locations read or written.
-
-  Segments
-    A list of segments headed by an embedded malloc_segment record
-    representing the initial space.
-
-  Address check support
-    The least_addr field is the least address ever obtained from
-    MORECORE or MMAP. Attempted frees and reallocs of any address less
-    than this are trapped (unless INSECURE is defined).
-
-  Magic tag
-    A cross-check field that should always hold same value as mparams.magic.
-
-  Max allowed footprint
-    The maximum allowed bytes to allocate from system (zero means no limit)
-
-  Flags
-    Bits recording whether to use MMAP, locks, or contiguous MORECORE
-
-  Statistics
-    Each space keeps track of current and maximum system memory
-    obtained via MORECORE or MMAP.
-
-  Trim support
-    Fields holding the amount of unused topmost memory that should trigger
-    trimming, and a counter to force periodic scanning to release unused
-    non-topmost segments.
-
-  Locking
-    If USE_LOCKS is defined, the "mutex" lock is acquired and released
-    around every public call using this mspace.
-
-  Extension support
-    A void* pointer and a size_t field that can be used to help implement
-    extensions to this malloc.

-  For security, the main invariant is that malloc/free/etc never
-  writes to a static address other than malloc_state, unless static
-  malloc_state itself has been corrupted, which cannot occur via
-  malloc (because of these checks). In essence this means that we
-  believe all pointers, sizes, maps etc held in malloc_state, but
-  check all of those linked or offsetted from other embedded data
-  structures.  These checks are interspersed with main code in a way
-  that tends to minimize their run-time cost.
-
-  When FOOTERS is defined, in addition to range checking, we also
-  verify footer fields of inuse chunks, which can be used guarantee
-  that the mstate controlling malloc/free is intact.  This is a
-  streamlined version of the approach described by William Robertson
-  et al in "Run-time Detection of Heap-based Overflows" LISA'03
-  http://www.usenix.org/events/lisa03/tech/robertson.html The footer
-  of an inuse chunk holds the xor of its mstate and a random seed,
-  that is checked upon calls to free() and realloc().  This is
-  (probabalistically) unguessable from outside the program, but can be
-  computed by any code successfully malloc'ing any chunk, so does not
-  itself provide protection against code that has already broken
-  security through some other means.  Unlike Robertson et al, we
-  always dynamically check addresses of all offset chunks (previous,
-  next, etc). This turns out to be cheaper than relying on hashes.

-/* -------------------- Alternative MORECORE functions ------------------- */
-
-/*
-  Guidelines for creating a custom version of MORECORE:
-
-  * For best performance, MORECORE should allocate in multiples of pagesize.
-  * MORECORE may allocate more memory than requested. (Or even less,
-      but this will usually result in a malloc failure.)
-  * MORECORE must not allocate memory when given argument zero, but
-      instead return one past the end address of memory from previous
-      nonzero call.
-  * For best performance, consecutive calls to MORECORE with positive
-      arguments should return increasing addresses, indicating that
-      space has been contiguously extended.
-  * Even though consecutive calls to MORECORE need not return contiguous
-      addresses, it must be OK for malloc'ed chunks to span multiple
-      regions in those cases where they do happen to be contiguous.
-  * MORECORE need not handle negative arguments -- it may instead
-      just return MFAIL when given negative arguments.
-      Negative arguments are always multiples of pagesize. MORECORE
-      must not misinterpret negative args as large positive unsigned
-      args. You can suppress all such calls from even occurring by defining
-      MORECORE_CANNOT_TRIM,
-
-  As an example alternative MORECORE, here is a custom allocator
-  kindly contributed for pre-OSX macOS.  It uses virtually but not
-  necessarily physically contiguous non-paged memory (locked in,
-  present and won't get swapped out).  You can use it by uncommenting
-  this section, adding some #includes, and setting up the appropriate
-  defines above:
-
-      #define MORECORE osMoreCore
-
-  There is also a shutdown routine that should somehow be called for
-  cleanup upon program exit.
-
-  #define MAX_POOL_ENTRIES 100
-  #define MINIMUM_MORECORE_SIZE  (64 * 1024U)
-  static int next_os_pool;
-  void *our_os_pools[MAX_POOL_ENTRIES];
-
-  void *osMoreCore(int size)
-  {
-    void *ptr = 0;
-    static void *sbrk_top = 0;
-
-    if (size > 0)
-    {
-      if (size < MINIMUM_MORECORE_SIZE)
-         size = MINIMUM_MORECORE_SIZE;
-      if (CurrentExecutionLevel() == kTaskLevel)
-         ptr = PoolAllocateResident(size + RM_PAGE_SIZE, 0);
-      if (ptr == 0)
-      {
-        return (void *) MFAIL;
-      }
-      // save ptrs so they can be freed during cleanup
-      our_os_pools[next_os_pool] = ptr;
-      next_os_pool++;
-      ptr = (void *) ((((size_t) ptr) + RM_PAGE_MASK) & ~RM_PAGE_MASK);
-      sbrk_top = (char *) ptr + size;

-      * Re-tuned and fixed to behave more nicely with V2.6.0 changes.
-      * Removed all preallocation code since under current scheme
-        the work required to undo bad preallocations exceeds
-        the work saved in good cases for most test programs.

-
-  The "chunks" argument is optional (i.e., may be null, which is

-  an array of pointers to these elements, each of which can be
-  independently freed, realloc'ed etc. The elements are guaranteed to

-  null, it returns a chunk representing an array with zero elements
-  (which should be freed if not wanted).
-
-  Each element must be freed when it is no longer needed. This can be
-  done all at once using bulk_free.
-
-  independent_comallac differs from independent_calloc in that each
-  element may have a different size, and also that it does not
-  automatically clear elements.
-
-  independent_comalloc can be used to speed up allocation in cases
-  where several structs or objects must always be allocated at the

-
-  struct Head { ... }
-  struct Foot { ... }
-
-  void send_message(char* msg) {

-    char*        body = (char*)(chunks[1]);
-    struct Foot* foot = (struct Foot*)(chunks[2]);
-    // ...

-
-  In general though, independent_comalloc is worth using only for
