Yes, that's it! mcedit failes after F10 if I used Ctrl + O earlier.
Sometimes it's not even a stackdump, but an infinite loop with 100% CPU
usage.

F11 causes a crash as well.

I've compiled MC-4.6.1-pre4 and tested it with this case. It crashes. I
failed to crash the same version on a Linux box this way, though.

Thanks for investigating it! Is there a cure? Please let me know if you
find one.
