gcc bug? constinit does not require constexpr ctor

[Klaus Doldinger <klaus.doldinger64@xxxxxxxxx>]

Hi all,

simple question: should in the following example the constinit case be
also impossible if the required ctor is not constexpr?

struct B {
    /*constexpr*/ B() {}
};

struct A {
    constexpr static inline B b2{}; // not possible
    constinit static inline B b1{}; // should this NOT possible either?
};

int main() {
    A a;
}
