Ticket 7: Segmentation fault at mod_mm.c:186

Hello,

I have compiled apache the latest apache 1.3 with php 4.2.3 and lib mm. After several hours, I get a seg fault of apache processes which originate from mod_mm.c at line 186.

It seems that php tries to retrieve a correct session id from libmm, but for some reason, it crashes in the for loop in mod_mm.c. Here is a gdb trace.

Program received signal SIGSEGV, Segmentation fault. 0x40356f4c in ps_sd_lookup (data=0x8082690, key=0x816da24 "0922ecff590e004d7a75919ac38dde0a", rw=0) at mod_mm.c:186

186 for (prev = NULL, ret = data->hash[slot]; ret; prev = ret, ret = ret->next)

(gdb) bt #0 0x40356f4c in ps_sd_lookup (data=0x8082690, key=0x816da24 "0922ecff590e004d7a75919ac38dde0a", rw=0) at mod_mm.c:186
