Provided save consistently crashes vanilla v0.44.12 on windows too.

And no, there isn't a version with debugging symbols, and Toady doesn't know how to get anything useful out of a crash dump. Thus, given Loci's confirmation of the save crashing, the next step will probably be Toady examining the save.

I've just ran into similar problem. Got a save that reliably crashes in a specific moment. Burrowing dwarves to stop all their activities seemingly prevents crashing, so it's jobs related. I'll try to research this.

Update: so i let the game run for a minute and then saved again to get it closer in time to the crash, but after reload it stopped crashing. Nevermind i guess.

Copying a reliably crashing game before saving again would be a way to allow investigation without risking losing the crash condition. Anyway, thanks for trying to pin the issue down.

I'm seeing what's possibly the same (or related) issue.

I have a save (uploaded to http://dffd.bay12games.com/file.php?id=14078 [^]) that crashes intermittently. No specific trigger, unfortunately, but it's crashed 12 times so far in the week or so since I've started it, and the crashes seem to be happening more frequently (3 today).

The uploaded zip has the save file as well as all the Diagnostic Reports generated by macOS for the crashes, in case they help.

All of the crashes are type EXC_BAD_ACCESS (SIGSEGV) with most being code KERN_INVALID_ADDRESS at some location.

This save (http://dffd.bay12games.com/file.php?id=14079 [^]), of the same fort but a short time later, crashes after about 2 minutes. Launch DF, load fort, do nothing, crash. Repeated three times on my machine.

I removed previous messages to summarize my attempts in shorter one.

This save will crash with segfault. Steps to reproduce:

[m]ilitary -> [c]reate squad, no uniform, add any dwarf if squad is empty -> [e]quip, [G]loves, choose any option and let the game run. "Specific gloves" shows completely unrelated list of items any of which cannot be selected. There isn't a single handwear item in the fort, but it crashes regardless.

risusinf's save is an easy-to-reproduce case of 0011014 - I analyzed this a bit from the DFHack side in https://github.com/DFHack/dfhack/issues/1678#issuecomment-732669641 [^]
