163 xrealloc on the results of such functions results in a crash.
165 One solution for this could be to define SYSTEM_MALLOC here, but
166 that does not currently work on this system.
168 It is possible to completely override the malloc implementation on
169 AIX, but that involves putting the malloc functions in a shared
170 library and setting the MALLOCTYPE environment variable to point to
173 Emacs currently calls xrealloc on the results of get_current_dir name,
174 to avoid a crash just use the Emacs implementation for that function.
