I hope that someone has seen this one before, because I am stumped.
I'm running NetHackl 3 at patch level 2 on a Xenix 386 system running SCO
Xenix 2.3.2. Sometimes, and it *always* happens while fighting a monster,
I'm simply thrown back out to the shell. No core dump, no message, no nothing.
This is exceedingly annoying, to say the least.
If you have an answer for me, I would *sure* love to hear it!!

I'd put good money that you are an exuberant fighter... You're hitting ! (exclamation mark) - it is a design feature. You are not being thrown "back" to the shell. You are nesting "into" a shell. Simply exit from the shell and you will be back in the game. Since the fighting isn't in realtime you might want to slow down the combat (and hence the keystrokes)... Fun time waster eh?

Sorry, but that really isn't the case. I have the same problem; sometimes I don't even have to actually attack, just wait to _be_ attacked and I'm dumped out. We're talking bug here, not OE (operator error). Besides, when was the last time anyone accidentally hit the ! key? I'd also love to hear of a fix for this one. -- Scott Reynolds rutgers!mailrus!clip!clmqt!scott Enterprise Information System scott@clmqt.marquette.Mi.US "Insufficient facts always invite danger." -- Spock

The prompt appears in the middle of the screen (it does not clear the screen like when I hit the '!' key) and I do a ps to find that this is indeed my login shell.

I've seen similar behaviour, except that Xenix says 'Illegal instruction'. Again, it happens only during fights.

Again, it happens only during fights. Anyone? I used to see this all the time on Nethack 3, but it has disappeared with Patch 2. At least I think it has; after several hours of play by myself and a couple of other players, no one has reported it. -- Karl Denninger (karl@ddsw1.MCS.COM, <well-connected>!ddsw1!karl) Public Access Data Line: [+1 312 566-8911], Voice: [+1 312 566-8910] Macro Computer Solutions, Inc.

Anyone? Happens in fights right after a hit which would have killed your opponent and given you (the player) a new experience level. This arises from a bug resulting in incorrect object code for the sequence MOVSX esi, al. It instead emits the sequence for a different destination register, then proceeds as if ESI had been loaded; eventually IDIV esi results in a division-by-zero exception. Cf exper.c:newexplevel where the character receives increased spell energy. -- Ben Goetter microsoft!beng blah blah blah blah disclaimer blah blah blah

Again, it happens only during fights. Anyone? I partly tracked this down on a friend's 386 Xenix machine. The illegal instruction is really "mod by zero" in rnd(), because rnd(0) was called from newexplevel(). It (almost) always happens in fights because killing a monster is the primary way of gaining experience to go up a level. This doesn't make any sense, though, because for rnd(0) to be called, SPELLS has to be configured, and WIS has to be negative. As shown on the screen, it wasn't even close to negative, and the game isn't supposed to allow it below 3. There may be wisdom-draining monsters, but not this early in the dungeon. I stuck code into rnd() similar to: if (x == 0) { pline("Some bozo code called rnd(0) again"); return 1; } along with some debugging code to print WIS. This prevents crashing the game but doesn't hide the problem. Debug printouts of WIS before and after indicate it's perfectly normal. Versions & other stuff: It bombs on 386 Xenix (not sure which version), Nethack 3.0, patchlevels 0, 1, and 2, and generally takes less than 20 minutes for my friend to demonstrate on request. It does NOT bomb on 68000 Xenix (int = 32 bits, if that's relevant), Nethack 3.0, patchlevels 0, 1, and 2, in spite of too much time playing the game. Minimal changes were made to the source on both systems. The special features that take memory were left in. Both systems are more-or-less "System V". About the most serious change was taking out the declaration of sprintf(), since it conflicted with include files, and changing the suffix assumed to be used by compress to match the version on my system.
