This just happened to me again.

I had several X11 frames open, most local and one remote. In a local
window I was invoking this function, which kills a set of buffers based
on their file names:

  (defun kill-buffers-under (dir)
    (interactive "GKill buffers under directory: ")
    (setq dir (file-name-as-directory (expand-file-name dir)))
    (mapc (lambda (b)
            (let ((file-name (buffer-file-name b)))
              (if (and file-name
                       (same-or-parent-dir-p (file-name-directory file-name)
                                             dir))
                  (kill-buffer b))))
          (buffer-list)))

I entered the directory name in the minibuffer, after I hit return,
Emacs crashed. Once again, redisplay_window is calling marker_position,
on a marker with position 9 in an empty echo-area buffer.

The "xbacktrace" command doesn't work on a core file, of course, but
manually walking the pdl stack I get:

"redisplay_internal (C function)"
"redisplay"
"sit-for"
"execute-extended-command"
"funcall-interactively"
"call-interactively"
"command-execute"
