Test case for assertion #13 of the sigaction system call that verifies
signal-catching functions are executed on the current stack if the
SA_ONSTACK flag is cleared in the sigaction.sa_flags parameter to the
sigaction function call.
NOTE: This test case does not attempt to verify the proper operation
of sigaltstack.
