[Bug c++/44625] [4.3/4.4/4.5/4.6 Regression] ICE after error: anonymous struct not inside named type

["rguenth at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #3 from rguenth at gcc dot gnu dot org  2010-06-22 11:08 -------
Reduced testcase (but with more and slightly different errors)

template<typename FP_> class Vec {
    Vec& operator^=(Vec& rhs)     {
        union {
            struct {FP_ x,y,z;};
        };
        X = y*rhs.z() - z*rhs.y();
    }
    Vec& operator^(Vec& rhs) {
        return Vec(*this)^=rhs;
    }
};
Vec<double> v(3,4,12);
Vec<double>V(12,4,3);
Vec<double> c = v^V;
