> To replicate:
>
> Compile the latest GNU 24.5.1 source tarball using:
>
> CFLAGS='-O0 -g3' ./configure --enable-checking='yes,glyphs' --enable-check-lisp-object-type --with-x-toolkit=lucid
> make
> cd src/
> gdb ./emacs
>   (gdb) run -Q -nw -f server-start
>
> In a separate terminal:
>
> x=0; while emacsclient -c; do x=$(( $x + 1 )); done; echo "Created $x windows before crash."
>
> Close each Emacs client window after it appears. Eventually (it seems to average about 5 tries) Emacs will hang with a partially-drawn window. No interaction with the UI is possible. At that point in another terminal I execute:
