Summary0011035: Crashes every time during save
DescriptionThe only thing weird I know of is that I sent off a raiding party on 16th malachite 260, and haven't heard from them in a while, and I'm wondering what happened to them.
Steps To ReproduceLoad the game, save, watch it crash. Has successfully crashed for me my last 5 tries. Last time was the only time I did nothing but save. No unpausing.

Save file: http://dffd.bay12games.com/file.php?id=14262 [^]
Additional Informationdf_44_12_linux.tar.bz2, no mods or utilities. World also generated with this version.

$ md5sum df
0d39ef03565df4fa13f9fec3bf1493b0 df

errorlog.txt always contains exactly "removed erroneous unit occupancy flag" 6 times.

Memory usage while saving (these lines repeated identically a bunch of times):

$ while : ; do ps auxww | grep "sh \./df"; sleep 2 ; done

$ while : ; do ps auxww | grep "sh \./df"; sleep 2 ; done

This is my first time playing dwarf fortress.

Oh, I also have over 360 animals. And it's running at 17fps. I had just queued up lots of slaughtering to try to fix this when it crashed for the first time (this way).

I have 4 1.3 gigabyte dump files, if you want them.

Running on MacOS, no crash was experienced by 7-12.

However, looking at the save shows evidence of armor list corruption as per 0011014. The offending item is SodelKudust, an electrum slab and the first entry in scrolls, codices, etc in Legends mode. No other armor list corruption is present.

0011014 crashes on play, this one crashes on save in the same manner as 0011030 and two saves from 0010939 (gdb backtrack is the same for these four saves). However still can be related, who knows in how many ways those vicious corruptions might bite your ass off.
