Most of my testing was on GZDoom 3.2.5, and while I have not managed to reproduce the crash with any reliability, I can say enough to know it's persisted on versions as new as 3.3.0. I know it still exists - I just don't know where. The only commonality between any of the crashes I've had reported to me is that it occurred as the player died, but player death in itself is not enough to crash it.
