Indeed. I've forgotten to describe the symptoms if not running under
gdb, and they are the same (visible bell while moving the mouse or
pressing any key, but no reaction otherwise; I had to kill Emacs, or
it crashed after some time).
Meanwhile could you try the patch I earlier sent to Sam. I'll attach it.
Basically, it should help to find the bug earlier.
