crash in CVS 2004-06-01

[Werner LEMBERG]

See below for a (partial) backtrace.  I still have the process for
further investigation if necessary.

The error suddenly appeared; Emacs has run a few days without any
other problems.

I've seen some patches to xdisp.c; maybe this problem is known and has
been fixed meanwhile?
