--- Comment #7 from Ville Voutilainen <ville.voutilainen at gmail dot com> ---
This is invalid. [namespace.udecl]/3 says that if the declaration names
a constructor, the nested-name-specifier shall name a direct base, but if
the declaration names something else than a constructor, indirect bases are
fine. The name is looked up by member name lookup, which will look in A first,
and
the hiding in B does not matter. Clang agrees with this interpretation.
