   Any game, it seems.

   Also, switching JIT<->interpreter doesn't crash. I think the IR interpreter doesn't clean up after itself properly.

   Yeah, the problem is confined to the IR interpreter, it's not cleaning up after itself. Switching back and forth between regular interpreter and IR interpreter has a similar result.
