    This appears only when we run pylint from "logilab" or when astng is a symbolic link /home/user/astng -> ~/src/logilab/astng.

    What happens is:

    • some astng modules (like builder and patchcomptransformer) go two times into the manager._cache, one time as "<module>", the other as "logilab.astng.<module>" .
    • the patchcomptransformer generates situation where a Class seems to be its own grandparent
    • but now the grandparent is the class with same name of the other "patchcomptransformer" module; hence we get a loop of length 4 and don't catch the grandpa situation which is usually catched in the ancestors method
