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)

More information was requested, but none was given within 7 weeks, so
I'm closing this bug.  If this is still an issue, please reply to this
email (use "Reply to all" in your email client) and we can reopen the
bug report.
