3590 dnl On AIX Emacs uses the gmalloc.c malloc implementation. But given
3591 dnl the way this system works, libc functions that return malloced
3592 dnl memory use the libc malloc implementation. Calling xfree or
3593 dnl xrealloc on the results of such functions results in a crash.
3595 dnl One solution for this could be to define SYSTEM_MALLOC in configure,
3596 dnl but that does not currently work on this system.
3598 dnl It is possible to completely override the malloc implementation on
3599 dnl AIX, but that involves putting the malloc functions in a shared
3600 dnl library and setting the MALLOCTYPE environment variable to point to
3601 dnl that shared library.
3603 dnl Emacs currently calls xrealloc on the results of get_current_dir name,
3604 dnl to avoid a crash just use the Emacs implementation for that function.
3606 dnl FIXME We could change the AC_CHECK_FUNCS call near the start
3607 dnl of this file, so that we do not check for get_current_dir_name
