--- Comment #2 from Bob Miller <bobmiller at nvidia dot com> ---
Apologies, I should have reduced this test case further before submission, but
I was under the mistaken impression that the template weirdness was the cause.
I believe this is a minimized example: https://godbolt.org/z/s3vGEh4Wx

template<int d>
struct S_Base
{
    static constexpr int D = d;
};

template<int d>
struct S : public S_Base<d>
{
    using S_Base<d>::D;
    constexpr void f() const
        requires(D > 0) {}

};

int main(int, char**)
{
    S<1> s;
    s.f();
    return 0;
}
