crash backtrace

[Chris Moore]

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

I started a new Emacs process as usual.

The first thing I did was type "M-x root RET".  The 'root' function
is defined in my .emacs:

      (defun root ()
        (interactive)
        (dired "/su:address@hidden:/"))

I typed the root password, saw a bunch of messages from tramp, as
usual, but then Emacs seemed to lock up.  I checked the GDB session
that I habitually run Emacs in, and found that Emacs had abort()ed.

I pulled the latest sources from CVS and build on 2004-02-03, so it's
not exactly a current build.  I had been seeing this function cause
crashes a lot when I first built Emacs.  After a few crashes I started
making sure that I always run Emacs inside GDB.  That seemed to fix
the problem - until now.  I'll recompile with the latest sources and
see if it happens again.

Perhaps someone will be interested to see the stack trace from the
crash:
