If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
`bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file

Do you have a way to reproduce this crash? I can't trigger it.
Looking at your backtrace, it looks like the crash is coming from deep
in xlib, so it may or may not be an Emacs bug.

It is as simple as
emacs -Q
M-x make-frame-on-display RET some_host:0 RET

I'm using Ubuntu 8.10, which IIRC uses the latest XOrg release.

Can anyone reproduce this? I currently don't have access to a computer
setup to test make-frame-on-display for remote hosts.
Oscar, could you try compiling without optimizations (CFLAGS="-g") and
gettting a backtrace again?
