--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Here is one slightly more reduced, removing range_t struct even:
template<double setup> struct knob_t {
int value = setup;
};
struct Helpers
{
knob_t<1.0> inputs;
};
template <class T, int N> auto h() noexcept -> decltype(sizeof(T{}));
int t = h<Helpers>();
---- CUT----
