Subject: bug#4040: 23.1; before-string overlay causes error when scrolling
Date: Wed, 05 Aug 2009 00:51:05 +0200	[thread overview]
Message-ID: <m2zlaf8a7a.fsf@igel.home> (raw)

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.

Andreas.
