--- Comment #2 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
Ok I think I see what the problem is. Before r230629, in
tsubst_pack_expansion, we'd go the convert_from_reference way even for
"sizeof...". And convert_from_reference entails mark_exp_read call. But since
that rev, we optimize and skip the convert_from_reference call thus even the
mark_exp_read call.
Shouldn't be terribly hard to fix, thus mine.
