--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Reduced to:
```
template <int N>
struct number {
    static constexpr int n = N;
};
auto sum(auto... ns) {
    return number<6>{};
}
auto f(auto... ns) {
    using T = decltype(sum(ns...));
    return []<typename N>(N n) requires(6 == T::n) {};
}

int main() {
    f(number<1>{})(number<6>{});
}
```
