The current Moose build from https://ci.inria.fr/moose/job/moose-6.1 no longer works and there is the following error when creating a Famix model:

- "AssertionFailure: Link to opposite links should be a bijective operation... Please check your model!"

This is caused by `FAMIX.BehaviouralReference.pointed` and `FAMIX.BehaviouralReference.referer` that point to attributes in FAMIXBehaviouralEntity that are not there.

They were added by Famix-CPlusPlus that is now loaded by ConfigurationOfFamix.

Are there some commits missing that add the missing functionality to FAMIXBehaviouralEntity?

Or should we remove for now `Famix-CPlusPlus` from ConfigurationOfFamix? 

Cheers,

Andrei
