"In fight against Ibun I got assertion fail
in a long corridor shooting arrows on Ibun. He spelled a lot and a cold vortex behind him kept breathing on both of us. Somewhat south of map center." - Thraalbeast
This is in square_istrap() - looks likely that this is called sometimes on grids that need not be in bounds.
