--- Comment #3 from klaus.doldinger64 at googlemail dot com ---
Here ist a simplified version of a MCVE:

template<int>
struct X {
    static constexpr int x = 0;
    static constexpr int y = 1;
};

template<>
constexpr int X<1>::x = 2; // should be ok, but gives duplicate initialization
error
template<>
constexpr int X<1>::y; // should be ill-formed (constexpr must be initialized),
but gives undefined reference

int main() {   
    return X<1>::x + X<1>::y;
}
