I compiled the latest version of the code and started a game. About halfway through (1967) it crashed after a mission. I had two missions scheduled and the game segfaulted after seeing the mission result screen. The stdout says simply "Segmentation fault (cord dumped)". I loaded the autosave and tried again. This time it got past that but crashed on the second mission. I restarted the game and loaded the autosave, then saved it and when I saved the game it crashed again. I've attached my autosave and the save I made.
