Emacs crash in X

Emacs crash in X

[Satyaki Das]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

In GNU Emacs 21.2.1 (i686-pc-linux-gnu, X toolkit, Xaw3d scroll bars)

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

I started emacs in gdb as follows:
  $ gdb /usr/bin/emacs
  (gdb) run  -q --no-site-file

Then I created a second frame with:  C-x 5 2

I move the new frame to a different workspace (it is important
to move it to a different workspace as moving it to a
different viewport in window managers that support both
doesn't cause the crash). At this point I have two frames both
displaying the *scratch* buffer.

In the new frame I load ~/pp.el with: C-x C-f ~/pp.el RET
Contents of ~/pp.el:

-- start of pp.el --
(progn
  (setq focus-follows-mouse nil)
  (select-frame-set-input-focus
   (window-frame (get-buffer-window "*scratch*" t))))
-- end of pp.el --

Now I move to the end of pp.el and evaluate the lisp
expression with: M-> C-x C-e

This causes Emacs to die. In gdb from where emacs was started
I see the following output:

X protocol error: BadMatch (invalid parameter attributes) on protocol request 42
Program exited with code 0106.

I use the metacity window manager. I have been able to
reproduce the exact same crash with CVS version of emacs that
I checked out on 2002-12-25. That version reports its version
as 21.3.50.3.

I came across this problem while using ILISP which is an
interface to various implementations of Common Lisp. I
minimized the code that needed to be run to crash emacs.

Hope this helps,
Satyaki
