And another bug/feature. In Ultimate Doom, E2M4 there is a small room with some nice stuff. When you cross the entrance, a part of the floor is raised to block the exit. But if you somehow stay on this part, you'll be trapped in this sector with no way out. GZDoom in this case will kill you, just like with a normal crusher, Chocolate, on the other hand, will also trap out, though another way. That's why I'm not sure if it's a bug, or simply normal Tech1 behavior.
