--- Comment #8 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
A slightly more reduced:
int h(int);
template <int dim>
  auto hh() { return 0; }
template<int a>
void mm() {
        const unsigned num_elements = 1;
        constexpr int dim = 1;
        [&]() {
                typedef decltype(hh<dim>()) derivative_type;
                h(num_elements * 1);
        };
}
void u()  {
        mm<1>();
}
