114 /* On AIX Emacs uses the gmalloc.c malloc implementation. But given
115 the way this system works, libc functions that return malloced
116 memory use the libc malloc implementation. Calling xfree or
117 xrealloc on the results of such functions results in a crash.
119 One solution for this could be to define SYSTEM_MALLOC here, but
120 that does not currently work on this system.
122 It is possible to completely override the malloc implementation on
123 AIX, but that involves putting the malloc functions in a shared
124 library and setting the MALLOCTYPE environment variable to point to
127 Emacs currently calls xrealloc on the results of get_current_dir name,
128 to avoid a crash just use the Emacs implementation for that function.
