--- Comment #1 from Nathaniel Shead <nshead at gcc dot gnu.org> ---
Confirmed. We error when reading an unnamed 'tt_data_member' for 'Derived'; it
looks to be that we missed handling using-decls on stream-in here. The
following patch fixes the issue locally, I'll test it more thoroughly and
submit when I get a chance:
