I was able to reproduce something similar in win32 by setting
the console to 21 rows. As he stated, don't let the game pick you
character for you to reproduce the problem. As soon as I chose
Archeologist the problem occurred:
Where:
In hack.c, weight_cap()
if (Levitation || Is_airlevel(&u.uz) /* <email deleted> */
#ifdef STEED
|| (u.usteed && strongmonst(u.usteed->data))
#endif
)
Variables:
carrcap 200
u.usteed 0x00000000
&u.uz 0x005e54aa
youmonst.data 0x00000000
Examination of the preprocessor output of that section
of code reveals that
"Levitation" becomes:
(u.uprops[47].intrinsic || u.uprops[47].extrinsic ||
((youmonst.data)->mlet == 5))
so it is the is_floater(youmonst.data) causing the crash.
Call stack:
weight_cap() line 2300 + 24 bytes
inv_weight() line 2342 + 5 bytes
calc_capacity(int 0) line 2354 + 5 bytes
near_capacity() line 2365 + 7 bytes
bot() line 607 + 5 bytes

tty_select_menu(int 5, int 1, mi * * 0x0006fc40) line 2248 + 9 bytes

pcmain(int 3, char * * 0x00a20eb0) line 457
main(int 3, char * * 0x00a20eb0) line 91 + 13 bytes
This adds a check for a valid youmonst.data in
bot().
