Probably not strictly related to the suggested repro, but anyway, it may crash the game.

save used:

Possible repro:
1. Load a save
2. Hit turn (Optional: Bash it like theres no tomorrow to make several turn advances.)
3. Immediately (When the game calculates a new turn) return to the menu and reload the save
I'm not sure if it's just my system, but it seems that stressing the game like that and reloading stuff can lead to crashes.
