Using Orca with LibreOffice, it is relatively easy to cause LibreOffice to

I was not aware of the segfault problems; I have not tested LibreOffice with
Orca on Ubuntu (or any other Linux distro).

For example, just to experiment with LibreOffice accessibility, I created a
new document, typed some text, selected "styles and formatting" (F11),
selected a header style, pressed enter and we crashed.

There are a few other LibreOffice bugs that mention Orca and crashes:
* Bug 36023 - LibreOffice writer crashes with Orca Screen Reader:
  "(...) Orca screen reader reads a portion of the complete text
  (when reading the whole document) and then Open/Libre office crashes
  with no warning or dialogue.
  As soon as trying to handle an object (such as an image) writer crashes
  immediately with no warning or dialogue. (...)"
* Bug 31973 - When ATs listen for object:children-changed:add events, 
LibreOffice crashes:
  "(...) The impact of this is that Orca users are seeing frequent crashes
   when working on documents, especially those with bullets/numbers. (...)"

Orca developers had to work around a similar issue recently, discussed on the
Orca list, with tables, which also caused segmentation faults in LibreOffice.

Is there a list of issues that cause crashes? Or even better, procedures to
reproduce the issues?

Someone who actually needs LibreOffice and who has the time should install
debug symbols and get stack traces.

Is there any guidance anywhere on how to do this?
