If the base is used in a map clause and later we have a memberexpr with this base, and the member is a pointer, and this pointer is dereferenced anyhow (subscript, array section, dereference, etc.), such components should be considered as overlapped, otherwise it may lead to incorrect size computations, since we try to map a pointee as a part of the whole struct, which is not true for the pointer members.
