Summary0009119: Program crashes a few seconds after unpausing loaded save
DescriptionAfter loading this save (and unpausing the game), Dwarf Fortress 0.40.24 (Windows, SDL) will cause a buffer overflow exception in a few seconds.

My hunch is that it might have something to do with the "mysterious construction" in progress in my sole craftsdwarf workshop, but I have no real idea.
Steps To ReproduceUsing the save available here:

http://dffd.bay12games.com/file.php?id=11297 [^]

1. Run Dwarf Fortress 0.40.24
2. On the main menu, select Continue Playing.
3. Select the only save. (Asenkes, Dwarf Fortress ; Boldoludon, 254 ; Folder: region1)
4. Unpause the loaded save.
5. The program crashes in a few seconds.

I did a little more research. You can prevent the bug from happening right away by setting the Civilian alert level to the custom alert I created and named !!DANGER!! This leads me to believe the error is happening because of a worker job.

After turning the Civilian alert level back to Inactive, the error will eventually occur again.

After watching the dwarves do their various tasks, I now suspect that the bug is related to the construction of a marble floor tile. Above the only Trade Depot on the map, the dwarves are building a marble "roof" out of floor tiles. Sometimes a dwarf will move across an unfinished portion of the floor and start constructing a floor tile in the middle, apprently not connected to anything. I now think this is causing the error.

Correct, you need to cut down both the pine tree and the willow north of your depo, the branches overlap the construction tiles causing a crash.
