Subject: 24.0.50; bidi-display-reordering interferes with overlays
Date: Tue, 20 Apr 2010 19:28:46 +0200

emacs -Q

Then evaluate in a scratch buffer:

(let ((ov (make-overlay (+ 2 (point-min)) (- (point-max) 160))))
  (overlay-put ov 'display "just a test")
  ;; (delete-overlay ov)
  )

(setq-default bidi-display-reordering t)
(setq-default bidi-display-reordering nil)

Note that when bidi-display-reordering is t, the text in the buffer is
displayed as well as the display property of the overlay, but when nil,
the text "just a test" is displayed instead.

Not just overlays, but display properties in general:

  emacs -Q --eval '(setq-default bidi-display-reordering t)' -f buffer-menu

and I suppose the problem with references in Info nodes is also related to this.

Thanks for the test cases, I fixed this now.

What problems?  If revno 100005 does not fix them, please file a new
bug report with a recipe to reproduce.

Thanks.
