Unfortunately the project causing the problem is proprietary. Sorry.

Comment 4 Aleix Pol 2012-01-19 15:41:52 UTC 
Well, it's possible that's already solved, or not.

If you can make another script to reproduce the problem, that would be helpful. Until then, I'm closing as invalid.
Comment 5 claas.koehler 2012-01-20 15:16:14 UTC 
I just pulled the latest trunk, and the problem still persists. I could not manage to create a simple test case, which shows similar behaviour.

Thus the problem is definitely not fixed and I suggest changing the status back to unconfirmed.

If I can assist you in debugging by providing more output or if you could point me in a direction, I could attempt to do further debugging myself, although I have to admit that I am not familiar with the kdevelop sources.

Regards
Claas
Comment 6 Aleix Pol 2012-01-20 15:19:08 UTC 
As I said, please provide a problematic example that I can reproduce.

With closed project, people usually provide the cmake sources without the C++, but of course the smaller it is, the better.
Comment 7 Milian Wolff 2012-01-20 16:46:10 UTC 
aleix, it's pretty easy to see that this might be an issue though just by looking at the sources: you do: list->elements().first(). What if elements() is empty? It asserts!

I think from that you should be able to construct a ListAst::Find unit test with empty elements, no?
