The problem here is that the variable which holds the object instance is not put in the members of the class objectInClass, it only exists in the tree. Therefore, AddInterfaces (which looks only at class members) doesn't see it, and doesn't leave it in the class.

To fix this bug, RefCheck should be fixed to include the variables it creates to store nested object's instances in the members of the enclosing class.
