That sounds like an issue with the X code which we might have fixed
already, but the fix hasn't been pushed yet.  Sorry about that.  I'll
let you know once I push.

If you have a coredump, you should save some place with the emacs binary
and the emacs.pdmp file.  You can then run

gdb <emacs executable> <coredump file>

(gdb) bt full

to get a postmortem backtrace.

That would be very helpful in this case.

Thanks for the report, and sorry if the bug has already been fixed.
