help debugging org-element crashes?

Hey everyone,

I'm finding my Emacs crashing a lot; other times I get errors like these
which I assume are related to the crashes:
http://pastebin.com/Tncs79r0
http://pastebin.com/jfdEYwVk

I mean total Emacs crashes, where I have to force quit Emacs itself. It's
happened in various org-mode situations including:
- pasting text from OSX clipboard
- promoting/demoting org-headings
- moving subtree up or down (i.e. using org-metadown org org-metaup)

My details:

Mac OSX Yosemite 10.10.5
GNU Emacs 24.5.1 (x86_64-apple-darwin14.5.0, Carbon Version 157 AppKit
1348.17)
Org-mode version 8.3.1 (8.3.1-129-ga7c8d2-elpaplus @
org-plus-contrib-20150921/)

I've tried reinstalling org-plus-contrib... I have also enabled
org-element-debug.

Any suggestions on how I can track this down and fix it?

Thanks!

I also experience frequent crashes at the moment and they happen in
similar situations.

I am in contact with an emacs dev to give him all the info needed to
sort out what is happening.

I would suggest that you file a bug report including backtrace of emacs
after the crash so that this can be followed up as a new bug or added as
additional data points to my bug report.

You could try to use HEAD - but I had the same crashes there.

You can see my bug report and tips on how to figure out what is
happening at https://debbugs.gnu.org/cgi/bugreport.cgi?bug=21428

Cheers,

Rainer

You could use this minor mode to track down the cache issue:

https://github.com/suvayu/.emacs.d/blob/master/lisp/org-element-debug.el

Once you know what triggers the crash, you can probably come-up with a
minimal example and post it here.

@Nicolas, others, do you think this should be on an FAQ on worg?

Not yet, please. I plan to change the internals of the cache at some
point, when I get sufficient spare time.
