Subject: Protect against timer triggers when no flymake-mode
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=555bea3615c2fb032c2b24ff6252e4322e9192d0;p=emacs.git

Protect against timer triggers when no flymake-mode

Not 100% sure on how to trigger this error, but it happened once or
twice, possibly during heavy debugging scenarios that wouldn't really
happen.  But a good idea anyway.

* lisp/progmodes/flymake.el (flymake-on-timer-event): Check flymake-mode
