The gdb output is as follows: You got further than my first memory overrun experience. It always crashed while resetting the zones. That was the overflow in the badname code. :) >#0 0x805041b in look_at_room (ch=Cannot access memory at address 0xbfffed7c. >) at act.informative.c:625 I doubt it was overwritten with text, note the 'ff' byte in there. Probably an array access though I may be wrong. >Now, NO ONE can log on. It must be somewhere in the starting functions >eh? eh? Now, if im right, anyone have a good guestimate where this >overwrite would be located? If I'm wrong, what would you do if you were >in my shoes? Try the mob_proto mprotect() patch I posted yesterday. If that doesn't work for you, try placing 'free(mob_proto);' (or whatever crashes for you) all over the code until you find the place before and after it crashes.
