I managed to crash the game, and find some bugs with objects, but I'm not sure exactly how. Here's what I did:
* Picked up a bunch of dropped equipment, including backpacks from my previous characters who had died.
* Went to a human town and tried to drop some rocks that seemed to be in the backpacks. It said I was dropping and throwing rocks from my inventory inside the packs, but the items were not being removed from my packs, though I could throw them and see a rock flying.
* Went underground in the human town and tried to drop the packs themselves. I think this is what caused the program to crash.
In another case after visiting the same cave after the crash (I hadn't saved the game since the previous character's death, so the giant-slayer seems not to have existed now), I suddenly noticed my speed had dropped. Studying my equipment, apparently it is because two of my pieces of clothing (backpack and wineskin, I think) have TURNED INTO FROGMAN CORPSES. I now have a frogman corpse on my back, and another on my belt... I then left the cave location (corpses still on), and walked one square on the overland map, and the program crashed again.
This is with some mods to the equipment files in place. I just adjusted some of the values of weapons, and added some weapons and armor types, and added references to them in entity_default.txt.
I had played a few characters to death before that started happening, though.
Edit: I am running 19b on Windows 2003 Server.
