--- Comment #3 from Marc Glisse <glisse at gcc dot gnu.org> ---
comment #1 actually reduces to
struct voider {
using type = void;
};
template <typename P> struct rename : P {};
template <typename> using ignore = voider;
template <typename T> typename ignore<typename rename<T>::type>::type g(T a) {}
void f() { g(1); }
(still questionable and rejected by clang, I think I'll also attach the
compressed initial preprocessed file, in case the reductions hit different
bugs)
