Subject: backtrace for errors that occur inside process sentinels
Date: Mon, 22 Dec 2014 20:43:02 +0100

Please provide a way to get backtraces for errors that occur inside
process sentinels.  Something similar to `toggle-debug-on-error', I
suppose.

This is a late follow up to
http://emacs.stackexchange.com/questions/3552/how-to-debug-errors-in-sentinels-and-during-font-lock

  Thanks,
  Jonas

(setq debug-on-error t) works for me:

   emacs -Q --eval '(setq debug-on-error t)'                          \
            --eval '(let ((proc (start-process "foo" nil "true")))    \
                      (set-process-sentinel proc (lambda (&rest args) \
                                                   (+ args 2))))'

brings up a *Backtrace* buffer just fine.

So this doesn't seem reproducible.  Jonas, do you have a recipe how to
trigger this bug?

More information was requested, but no response was given within a few
months, so I'm closing this bug report.  If the problem still exists,
please reopen this bug report.
