--- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Reduced:
int h(int);
template <int index, int dim, typename trials>
  auto get_derivative_type1() { return 0; }
template <typename test, typename trials>
void generate_kernels1() {
        const unsigned num_elements = 1;
        constexpr int dim = 1;
        [&](auto index) {
                using derivative_type = decltype(get_derivative_type1<index,
dim, trials>());
                h(num_elements * 1);
        };
}
void thermal_test()  {
        generate_kernels1<int, int>();
}
