Hi,
I found an issue where evaluating this line or not causes Emacs behaviour change:
(format "%s" marked-point)
"marked-point" is a marker. The bug was found on NTEmacs 23.2.1, reproed on CVS NTEmacs 20110111, and Stephen Berman confirmed it on GNU Emacs 24.0.50.1
(i686-pc-linux-gnu, GTK+ Version 2.20.1) of 2011-01-13 on escher
"rebox2_bug.el" is attached to this message.
Repro-steps:
- emacs -Q rebox2_bug.el
- M-x eval-current-buffer
- C-x b<enter> ;; switch to "*scratch*"
- M-x rebox-mode
-
M-<
- SPC,SPC ;; space twice
- C-aC-aC-aC-a ;; notice that the point is stuck at 6
- C-xb<enter> ;; switch to "rebox2_bug.el
- M-g g 1714
- C-d ;; uncomment the hack workaround the bug
- C-M-x ;; reevaluated the function
-
C-x b<enter> ;; switch to "*scratch*"
- C-aC-aC-aC-a ;; notice that the cursor switches between 1 and 6
rebox2_bug.el
