tried filing a bug through the emacs submit , but that was the last I ever heard of it. Here is the output:

I get crashes on the same line again and again:

There are two functions I've been using for years which allow me to
use the home and end keys as follows:

press once   goto beginning/end of line
press twice  goto beginning/end of window
press thrice goto beginning/end of buffer

Those functions are:

(defun chb-home ()
  (interactive)
  (if (not (bolp))
      (beginning-of-line)
    (if (eq this-command last-command)
        (cond
         ((not (= (point) (window-start)))
          (move-to-window-line 0)
          (beginning-of-line))
         (t
          (goto-char (point-min)))))))

(defun chb-end ()
  (interactive)
  (if (not (eolp))
      (end-of-line)
    (if (eq this-command last-command)
        (cond
         ((not (= (point) (save-excursion
                            (move-to-window-line -1)
                            (end-of-line)
                            (point))))
          (move-to-window-line -1)
          (end-of-line))
         (t
          (goto-char (point-max)))))))

I bind them like this:
(global-set-key '[(home)] 'chb-home)
(global-set-key '[(end)]  'chb-end)

Very convenient.

Regards,
Stefan

You hit. The format string crumbles and turns to dust.
