90 | /* On AIX Emacs uses the gmalloc.c malloc implementation. But given |
91 | the way this system works, libc functions that return malloced | |
92 | memory use the libc malloc implementation. Calling xfree or | |
c6ea2936 | 93 | xrealloc on the results of such functions results in a crash. |
3480d92b DN |
94 | |
95 | One solution for this could be to define SYSTEM_MALLOC here, but | |
96 | that does not currently work on this system. | |
97 | ||
98 | It is possible to completely override the malloc implementation on | |
99 | AIX, but that involves putting the malloc functions in a shared | |
100 | library and setting the MALLOCTYPE environment variable to point to | |
294c50a0 GM |
101 | that shared library. |
