Hi Stefan,
Thanks for the answer at first.
If is a bug, do you need more information in order to check it? Could you
tell me the methods that are used to merge the override declarations for
investigate by myself and create a patch to correct the bug?

Is there a workaround that maybe solve this?

King regards,
Alexandru
