--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
A related rejects valid testcase:
```
template <typename T=int>
void foo () {
        constexpr auto g = []() { return true; };
        auto lambda = [](auto x) -> int requires (g()) { return 0;};
        lambda(42);
}

int main()
{
  foo ();
}
```

Changing foo to a non-template and GCC accepts the code.
