What timing! It just happened again. Here's the stack dump out of dbx:

(dbx) where
>  0 _kill(0x3145, 0x6, 0x7fffaa50, 0x0) ["kill.s":15, 0xfae25d4]

   11 __start() ["crt1text.s":133, 0x4114ac]
(dbx) 

Comments: at the moment this happened, my char wasn't doing a darned thing,
just avoiding monsters while running through a new map. Sometimes it seems
like my char definitely causes the crash, but not this time.

I can't see any obvious goofs around the offending source lines, but then
I don't know much about the way the program is structured..

Hmm.. but in the stack trace.. The first parameter of change_abil looks fishy;
it's out of range. (compare with other pointers).. (I gather from looking
at the typedef of object in struct.h that op->env (line 127 in server/time.c)
is supposed to point to another object (or NULL), unless there's some
deliberate funny business going on somewhere).
