Can you please send a logfile of a crash? Behaiving weird is expected, with an
illegal pos - GUI and engine will not be able to communicate. But a crash should
of course not happen. Perhaps, in the future I will just close the engine.

I think, the GUI must handle this. There is no way in the UCI protocol (for good
reasons) for the engine to complain to the GUI for any illegal pos or move.
