Hello Martin,

I've never seen such crashes.  Hm.  Of course, having a
nonreproducible problem makes it more difficult to diagnose.

Can you run Emacs under the debugger?  That would help a lot, I think.

The procedure goes like this:

    cd ~/work/gnu/emacs/src
    gdb emacs
    run emacs ...your.args.here...

Instead of ~/work/gnu/emacs you should use your own CVS working
directory, of course.  The reason for changing to that directory
first is that it contains a .gdbinit file which helps with debugging
Emacs.

Now, when Emacs crashes, you ought to be able to get a C-level
backtrace using the normal gdb commands.  And you should be able to
get a Lisp-level backtrace, too, using the xbacktrace command
provided in .gdbinit.

You might also wish to look at the file ~/work/gnu/emacs/etc/DEBUG
which contains more information on debugging Emacs.

Does this help at all?
