5f095f5 is the first bad commit (for my use case)

[Sebastien Vauban]

Hello,

Since updating to latest Org this morning, I couldn't open anymore my file
~/org/work.org.

Symptom?  Org-mode gets loaded, but buffer remains blank, and Emacs is
(apparently) inflooping, with letting me stop it (with C-g).

Solution?  Kill Emacs through the task manager, and bisect:

  ╰────

Now, having my Git tip on commit 3f95d81, everything's OK. I can work again,
but the most difficult problem is that I don't see how to debug further the
above problem.

Any idea why this fails?

Best regards,
  Seb

Probably an infloop, as you suggest. It would be great if you could
provide an ECM (even not "M") for that problem. You can send it through
private mail if you want.

Also, what's your value for `org-highlight-latex-and-related'?

You've directly put me on the right track: some (untested) code I added just
before leaving on vacation...

--8<---------------cut here---------------start------------->8---
  ;; highlight LaTeX and related syntax
  (setq org-highlight-latex-and-related
        '('latex
          'script
          'entities))
--8<---------------cut here---------------end--------------->8---

This is obviously wrong (shame on me!), but has the interesting effect of
causing an infloop on opening Org files...

Thanks!

Best regards,
  Seb

I fixed the infloop. Thank you.

Thanks!

Do you know if there was a way out -- other than killing Emacs -- in such a
case where `C-g' is not working?

None that I can think of.

If you are on Linux (or OS X, I suppose), you can sometimes break an
infloop by sending emacs the SIGUSR2 signal (in the shell, “kill -USR2
`pidof emacs`”).  This also generates a backtrace in the lisp debugger,
which is useful for debugging.  See C-h v debug-on-event .

Is this with Emacs/24.2.91 on windows-nt?

Do you have this error with emacs -Q?
