I did recompile with full debug but unfortunately, I do not manage to
crash it with the same procedure. Everything is a lot slower however, so
maybe timing is important.
I suspected memory corruption as well as triggering the crash seems to
rely there being consideral memory load on the system.
Would valgrind help (you'd need to tell me how to run that with X
though)?
Reinstalling the non-debug version again and I can reproduce quite
easily again:
