Subject: bug#23245: 25.0.92; cua-mode inhibits deactivate-region-hook
Date: Fri, 08 Apr 2016 18:50:43 +0200

I noticed that https://github.com/fgallina/region-bindings-mode started
to fail to deactive from time to time after I swiched to the emacs-25
branch.

I think I have tracked the problem down to cua-mode being the thing
which causes this.

I have been able to reproduce this problem.  If i use the init.el below
and repeatadly activates and deactivates regions for a while an AM
is logged to the messages buffer without a DM following the
deactivation, after this (region-active-p) evaluates to nil but there
was to deactivation hook fired.

(defun AM ()
  (message "AM"))
(defun DM ()
  (message "DM" ))
(add-hook 'activate-mark-hook 'AM)
(add-hook 'deactivate-mark-hook 'DM)
(cua-mode)
