Evaluating this form signals an error:
ELISP> (with-temp-buffer
(switch-to-buffer (current-buffer))
(insert-char ?x (1+ (window-width)))
(let ((ovl (make-overlay (1- (point)) (point))))
(overlay-put ovl 'before-string " "))
(goto-char 1)
(scroll-up 1))
*** Eval error *** Args out of range: 0
It comes from get_char_property_and_overlay, which is called with
position == 0 by pos_visible_p.
