--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
See https://gcc.gnu.org/ml/gcc-bugs/2017-08/msg01667.html where I said:

I don't think this is a bug. B is the primary base class for Z so has already
been allocated (as part of the Y subobject, in I-2b), and so the B base class
of the X subobject is not allocated as part of the X (in III).
