[1.1.80] Crash Chunk::preSaveNonRecursive

[Valeskas]

Edit2: this machine failed memtester, so the report is useless.

Edit: somehow I missed a previous report: viewtopic.php?p=584391#p584391
So my report is a duplicate. Please delete if not needed.

I have a headless server running continously on a linux machine in a closet.
After updating to 1.1.80 it crashed a second time with SIGSEGV on autosaving. (First time was also on 1.1.80, I assumed it was a one time thing and next autosave went fine)
Client was alt-tabbed at the time of crash, and reported communication problem when I looked at it.
It probably was alt-tabbed the entire time between autosaves, but I am not sure.
Most action on the map is artillery attacking biters on the map edge, and trains delivering supplies for it.
No mods.
