74 | /* On AIX Emacs uses the gmalloc.c malloc implementation. But given |
75 | the way this system works, libc functions that return malloced | |
76 | memory use the libc malloc implementation. Calling xfree or | |
c6ea2936 | 77 | xrealloc on the results of such functions results in a crash. |
3480d92b | 78 | |
6259c2ec GM |
79 | One solution for this could be to define SYSTEM_MALLOC in configure, |
80 | but that does not currently work on this system. | |
3480d92b DN |
81 | |
82 | It is possible to completely override the malloc implementation on | |
83 | AIX, but that involves putting the malloc functions in a shared | |
84 | library and setting the MALLOCTYPE environment variable to point to | |
294c50a0 GM |
85 | that shared library. |
86 | ||

e05aebe9 | 88 | to avoid a crash just use the Emacs implementation for that function. */ |
