62 | /* On AIX Emacs uses the gmalloc.c malloc implementation. But given |
63 | the way this system works, libc functions that return malloced | |
64 | memory use the libc malloc implementation. Calling xfree or | |
c6ea2936 | 65 | xrealloc on the results of such functions results in a crash. |
3480d92b | 66 | |
6259c2ec GM |
67 | One solution for this could be to define SYSTEM_MALLOC in configure, |
68 | but that does not currently work on this system. | |
3480d92b DN |
69 | |
70 | It is possible to completely override the malloc implementation on | |
71 | AIX, but that involves putting the malloc functions in a shared | |
72 | library and setting the MALLOCTYPE environment variable to point to | |
294c50a0 GM |
73 | that shared library. |
74 | ||
3480d92b | 75 | Emacs currently calls xrealloc on the results of get_current_dir name, |
e05aebe9 | 76 | to avoid a crash just use the Emacs implementation for that function. */ |
