--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
here is one which removes the inner lamba to just a templated function inside a
template struct:

template<auto f>
struct h {typedef int type;};

template<class Types>
struct t{};

template<typename Ts>
struct crash {
    using Types = typename h<[]() {}>::type;
    template<int tt>
    static void f()
    {
        using type = t<Types>;
    };
};

int main() {
    crash<int>{}.f<1>();
    return 0;
}
