Prematurely sent (C-c C-s key-binding should be disabled in message
mode).

Anyway backtrace is now attached. Note that, `enable-multibyte-characters' was
set to nil when this happened.

Please show the information collected by "M-x report-emacs-bug RET" on
that machine with that Emacs version.

Also, is the Org manual the one from the Emacs repository, or from
elsewhere?  If the latter, please tell where to get it.

Thanks.

Sorry, please disregard this part, I misunderstood what you meant by
"cycling".

I guess this crash doesn't happen with every Org file, because I just
tried and it didn't crash.  Could you post the shortest Org file that
causes the crash, and also tell at what position in the file to try to
cycle visibility?

Please see cut down version of my org file.

When opened attached org as follows, it automatically crashes on my system. 
emacs -Q test.org -eval "(set-buffer-multibyte nil)"

Thanks.  That particular crash is fixed in trunk revision 115399, but
I'm not sure if it fixes your original use case (did you also toggle
buffer's multibyteness there, after visiting the file?).  If the
problem is not entirely fixed, please show the recipe to reproduce the
problem.

Thanks and I can confirm.

Yes.

I can't reproduce original problem now. I think we can close this bug now.
