--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Reduced testcase:
template<class... T> class Base{};
template<class... Ts> void error(Base<Ts> const &... args){}
template<class... Ts, class = void> void error(Ts &&... args){}
int main()
{
Base<int> const a;
error(a);
}
---- CUT ---
Looks like GCC takes into account the default template argument incorrectly.
