--- Comment #2 from Fedor Chelnokov <fchelnokov at gmail dot com> ---
Here is a valid code, accepted by other compilers, leading to the same ICE:
```
using V = decltype([](auto x) { x.f(); });

class A{
    void f() {}
public:
    friend constexpr auto V::operator()(auto) const;
};

int main(){
    V{}(A{});
}

```
