--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> ---
We also have constexpr on some std::complex constructors that should not be
constexpr until C++14:

  template<>
    class complex<float>
    {
    public:
      typedef float value_type;
      typedef __complex__ float _ComplexT;

      _GLIBCXX_CONSTEXPR complex(_ComplexT __z) : _M_value(__z) { }

      _GLIBCXX_CONSTEXPR complex(float __r =3D 0.0f, float __i =3D 0.0f)=
