I'm running CentOS 4.3 x86_64 on a dual opteron 246 system with 1 gig of ram, kernel 2.6.9-34.ELsmp.

Ser runs fine with quite a few modules, but when I enable acc.so, I immediately get a segfault.

I ran it under gdb and was able to obtain this information:

#0 0x0000002a9578516f in insert_tmcb (cb_list=0x0, types=1, f=0x2a955675c7 <acc_onreq>, param=0x0) at t_hooks.c:99 #1 0x0000002a95785494 in register_tmcb (p_msg=0x0, t=0x0, types=1, f=0x2a955675c7 <acc_onreq>, param=0x0) at t_hooks.c:166 #2 0x0000002a955674c7 in mod_init () at acc_mod.c:308 #3 0x0000000000430d79 in init_mod (m=0x5d5228) at sr_module.c:474 #4 0x0000000000430ce8 in init_mod (m=0x5d52e8) at sr_module.c:471 #5 0x0000000000430ce8 in init_mod (m=0x5d53a8) at sr_module.c:471 #6 0x0000000000430ce8 in init_mod (m=0x5d5468) at sr_module.c:471 #7 0x0000000000430ce8 in init_mod (m=0x5d5528) at sr_module.c:471 #8 0x0000000000430ce8 in init_mod (m=0x5d55e8) at sr_module.c:471 #9 0x0000000000430ce8 in init_mod (m=0x5d56a8) at sr_module.c:471 #10 0x0000000000430ce8 in init_mod (m=0x5d5768) at sr_module.c:471 #11 0x0000000000430e05 in init_modules () at sr_module.c:497 #12 0x0000000000416f3c in main (argc=3, argv=0x7fbffffa18) at main.c:1577

I also did a bt full:
