[O] Bug: org-occur with > 1 matches on a line causes 100% cpu lockup when next-line [7.8.11]

[ken restivo]

Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.  You don't know how to make a good report?  See

     http://orgmode.org/manual/Feedback.html#Feedback

Your bug report will be posted to the Org-mode mailing list.
------------------------------------------------------------------------

If there are > 1 org-occur matches on a single line, doing next-line on that 
line will cause emacs to lock up with 100% cpu usage.

Doing previous-line on the SAME line will cause emacs to show "Beginning of 
buffer" in the echo area, even if that line is very deep in the buffer (like, 
line 119, in the buffer I was using).

Problem does not happen with only ONE match per line. If there are > 1 matches 
on a line, it'll only lock up on that particular line, all other lines can be 
next-line'd or previous-line'd without problem.

The difficulty is that this causes org-mode to be fragile and dangerous, you 
never know when you'll hit that mine and emacs will go away and have to be 
restarted.
