I will try to catch this in the debugger, but attached here you'll find
three NS build crashes with the Mac OS X debugging info.

Anecdotally, I seem to get these crashes when I've run Gnus in the Emacs
instance and am using CUA keys to move (Ctrl-Shift-Up/Down).  The
crashes seem related to image memory management.  I can't replicate them
with emacs -Q.

Thanks
