Did a little more testing, I'm using Windows 7, 64 bit. I'm playing in ASCII mode, windowed. I first noticed the crash in the Puppy Cave, and then again in the Village Dungeon. I left the game open with the inventory screen open, left it while I was at work and came back just fine. Then went out to the world map, switched focus and had another crash.
I started up another game, went into the Village dungeon, saved, reloaded, switched focus and started timing on a stopwatch until I got the "adom.exe has stopped working" message. Did this 5 times and it was pretty consistently happening around the 1:25 mark.
Windows event viewer errors show the faulting module as either noteye.dll or SDL2.dll.
