I tried to use overlay-arrow-variable-list, but can't display more
than one fringe arrow in one buffer.  I tried the code below:

(progn
  (goto-char (point-min))
  (insert "abc\ndef\nghi\n")
  (setq overlay-arrow-position
        (copy-marker (save-excursion (forward-line -1) (point)))
        next-error-overlay-arrow
        (copy-marker (save-excursion (forward-line -2) (point)))
        compilation-overlay-arrow
        (copy-marker (save-excursion (forward-line -3) (point)))
        overlay-arrow-variable-list
        '(next-error-overlay-arrow compilation-overlay-arrow 
overlay-arrow-position)))

What is wrong with this?
