哪个 C++ 编译器对此代码有错误？

Question

以下内容由 gcc（12.1 和 trunk）编译良好，但 clang（14.0.0 和 trunk）在 上给出错误d.foo()，表示调用不明确。问题是，我应该向哪个编译器报告错误？

class Base
{
public:
  void foo() {}
};

class Derived: public Base
{
public:
  using Base::foo;
  void foo() & {}
};

int main()
{
  Derived d;

  // Clang says here: error: call to member function 'foo' is ambiguous. Gcc,
  // however, is fine with it
  d.foo();

  return 0;
}
