There's various ways you can help...
If you can test the feature and still get it to crash that helps (it shows us there is indeed still a problem).
If you can identify an easy way to reproduce it, that helps (it provides a testcase).
If you can identify what part if the code is crashing (logs & backtrace) that helps (we can see where the bug lies).
If you can spot the problem in the code and perhaps even contribute a patch that'd be enormously helpful
This appears to be the latest Jira bug ticket. From the last comment there it looks like the issue lies within the Sofia-SIP library. We could patch it and push a fix upstream, or perhaps this has already been corrected since the ticket is over 4 years old.
I guess the main reason no-one knows is that with that warning no-one has dared to test it on a production server. :)

It's all code, of course there are things that can be done.
