Summary

0001922: Crash when cancelling zone creation in floor flow mode

Description

I can reproducibly crash DF by setting zone creation to floor flow, laying out a zone, and then pressing esc to cancel out of creating the zone.

WORKAROUND: Don't use floor flow.

Steps To Reproduce

Go into zone designation mode and set it to floor flow.
Go to create a zone, maybe increase its size a few times, then hit escape to cancel zone creation. It does not always crash each time I do this, but it will reliably crash eventually if you hit enter, randomly mash + and - a few times, and hit escape. It may take upward of a dozen tries (or it may happen right away). It doesn't seem to correlate to any specific size or shape of the marked area when I cancel, but I do have to increase its size at least couple times to get it to happen; that is, mashing ONLY enter and esc (with no + or -) didn't seem to reproduce it (but given the occasional nature of the crash I can't say this conclusively). It doesn't seem related to whether or not I decrease the zone size as well as increase it. It doesn't seem to depend on where I do it; I tried a few places in my fort as well as points outdoors. It doesn't seem to happen in regular "flow" mode, just floor flow mode (but again, given the occasional nature of the crash, I may just have been unlucky when I tried to do it in floor mode).
It doesn't seem to be specific to a particular save. I genned a new world, did a quick "Play Now!" embark, and immediately crashed DF by cancelling a floor flow zone next to the wagon.

Additional Information

Sometimes DF just freezes when I do this and I need to kill it, but sometimes the program crashes and closes, dumping the following messages in the terminal:
