I'm trying to play a custom mapset in the '94 game Rise of the Triad: Dark War. Playing those maps on actual hardware, it does not crash at all. In DOSBox, at various parts of any level in the mapset, the game crashes with a Z_levelmalloc error about being unable to allocate (number differs with each crash, like 152) bytes. It gives no other information otherwise. I tried setting memsize up to 512, loadfix -256, but it makes no difference. Anything else I can try?
