*agree* I thought I did that... Maybe I forgot...
Anyway... dgb reported a crash here:
0x807eebd in check_fall () at limits.c:368
368 if (((SECT(IN_ROOM(ch)) == SECT_FLYING)) && (!AFF_FLAGGED(ch, AFF_FLY)) &&

and that's why i was pondering NULL pointers and everything... BUT!

I've started doing that after I wrote the message... And now I have a
proof, that only printing out last things in gdb and hunting for bugs just
with looking backtrace info... won't help me much..

The thing is, that mud crashes before that line gdb reports! *cringe*
*blink* *confuse* *bonk* *wtf*

Heck.. it's true...  stepping looked like this...

(gdb)
1164      else if (amount <= 10000)
(gdb)
1165        strcpy(buf, "a large heap of gold coins");
(gdb)
1181      return buf;
(gdb)
1182    }
(gdb)
Program received signal SIGSEGV, Segmentation fault.
0x807eebd in check_fall () at limits.c:368
368 if (((SECT(IN_ROOM(ch)) == SECT_FLYING)) && (!AFF_FLAGGED(ch, AFF_FLY)) &&

Which means... The ch was killed... corpse is beaing created... right now
the money is being created.... then when the money is created and we
should return back into make_corpse() and do a obj_to_obj() we just simply
crash... *blink*

Hm, Am I here on the right path to the solution? *scratch*

At least that's seems to me, like that mud is crashing upon exiting
create_money() and then in gdb just skips everything and BANG we et a
faulty report from crash..

David!
