<pre>struct B {
void f();
private:
B(int, int = 0);
};
struct D : B { using B::B; };
void B::f() {
auto a = D{0};
auto b = D(0);
auto c = D(0, 0);
D x{0};
D y(0);
D z(0, 0);
}
Accepts: b, x, y, z. Rejects: a, c.
MSVC accepts all in C++17 mode, rejects all in C++14 mode, which apparently [1]
is due to their interpretation of the C++14 as-published wording [2].
GCC accepts all since 7.1, previously rejects all.
