dch->pcdata->lastvnuma = dch->in_room->vnum;

(gdb) p dch->pcdata->lastvnuma
$1 = 0
(gdb) p dch->in_room->vnum
$2 = 744

The only odd thing (besides a crash caused by setting vnuma) is the buf, when info locals was done.

(gdb) info locals
dch = (CHAR_DATA *) 0x9671290
buf = "Bryan has accepted Touran's challenge!", '\0' <repeats 14 times>, "t?\000\000say \000\000\000\000doctor is quite a skilled healer. Everyone in the city knows that.\000\000say He often likes to collect a fee of 100 yen for his services, though."...

Anything here that can be seen causing the crash?

David Haley USA Thu 03 Mar 2005 08:30 PM #1

Strange bug. I'd check for make-clean/remake, or something like that.

Zeno USA Thu 03 Mar 2005 08:36 PM #2

Last make clean was the 1st, two days ago. Haven't modified any header files since then.

David Haley USA Thu 03 Mar 2005 09:20 PM #3

Afraid I can't help you here... it looks fine to me. Can you reproduce it?

Zeno USA Thu 03 Mar 2005 09:24 PM #4

Nope. If I could, I'd probably be able to fix it. Most of the crashes I can't reproduce, they seem to happen at random.

Samson USA Fri 04 Mar 2005 01:50 AM #5

I don't see anything wrong with what you've posted either. About the only thing I could come up with is that maybe one of the things being accessed is actually free'd memory that hasn't been cleaned up. I just went through a whole bunch of that :)

Zeno USA Fri 04 Mar 2005 03:36 AM #6

It might be. There are still a few bug fixes you found recently which I haven't applied. Or it could just be this arena snippet. Nothing but trouble for many weeks. Still issues.

Zeno USA Fri 04 Mar 2005 06:52 PM #7

Gah. 2nd time it's happened.
