Summary0008410: Crash due to zero-size weasel
DescriptionI understand I'm running Dwarf Fortress on a rather shitty PC, but this crash has never occurred before in my other 2 worlds, so I'm baffled.

I have an EXTREMELY OLD (at the moment) Hewlett-Packard Pavilion, Intel(R) Celeron(R) CPU 2.93HGz, with 504 MB of RAM. (It runs the game at a smooth pace, so It's good enough for me)

I don't think this is part of the problem, unless it is, but this error occurs only after a short time. To clarify when this crash was occurring, I saved the game after one of my animals grew into a "Stray Drake", but it would only happen about 3-5 minutes AFTER that happened, so I saved the game after it grew, and the time it took for the game to crash became shorter, where it took a good 10 minutes to the 3-5 minutes. This is the first time I've ever had a Stray Drake, so I'm wondering if that's the problem, but I can't even FIND the Stray Drake. Probably hidden.
NOTE: Tileset in use is the latest Pheobus.
Anyways; here's the save and the error reports I got:

I'll see if I can get the crash on my system, although mine is a hell of a lot newer, less than a year old.

Edit: It wasn't neccesary to copy the entire game folder, just the save folder is neccesary.

As for where the stray drake is, it's the only one in your fort and you're pratically looking at it on the spot where the game loads, it's the only unit in view with a flashing '?'

Edit2: Yep, crashes for me as well about or within 10 seconds of unpausing.

Okay, I checked if the drake had anything to do with it by killing it via DFhack, still crashes. It probably came with a migrant wave and you just didn't notice it.

At least it's a reproducible crash, no idea where to look for the cause.

Sorry, I notice it now. I guess in my frustration to discover the problem, I kept overlooking him.
Thanks for taking a look at my save, however.
My bad on giving you the entire game.
If it helps at all, something buggy was going on with my dwarves. I have a bunch of stuff designated to go into my Dump pile, but for some odd reason, some dwarves will try to grab those items to use in Metalwork or Masonry, doesn't really matter. There was a point that I had 3 dwarves at a time doing it. They go to grab it, and once they're over the object, they stop moving. They'll stand there until they die because they're rmtrying to obtain this item, but its designated towards the dump. The item doesn't even appear under them (even though it shows via flashing) until I cancel the job they're working on. Would that happen to possibly be a cause of this problem?

This is also the first save I've gotten where all the barrels and bins actually work, (my mistake for giving each pile a "reserved" amount) so if there's a way to save this save file, I'd appreciate the knowledge.

At the southwest corner of the map, there is a weasel which somehow has a body size of zero, and its reaction to being hunted by Dodok Momuztherleth the Cook is apparently resulting in a division by zero.

Said weasel appears to be just over 10 days old, which would normally put its body size at 2 (due to [BODY_SIZE:0:0:20]); presumably, random genetic variation caused it to be "smaller than usual" and reduced its body size all the way to zero.

If you have DFHack, type the command ":lua df.unit.find(1001).animal.vanish_countdown = 1" and then unpause - the weasel should vanish in a puff of smoke (just like a bogeyman) and the game should continue without crashing.

I saw the OPs full game save that they put up, he/she doesn't have DFhack. However, canceling the cooks hunting job should do the trick, although might want to cancel the other hunt jobs and turn off hunting for at least a season until said baby weasel leaves the map.

You could try siccing the military on it, but no telling what will happen, might even crash again.

I installed DFHack and took care of the pesky weasel. As much as I'd like to have obtained him, he is now gone and my fortress is now seemably crash free. Thank you for your help!
