operator<< segfault

I have had the following macro defined for several years (it worked through root versions 3 and 4), but with recent releases (5.13) it causes root to crash.

ostream& operator<<(ostream& out, const TLorentzVector v) {

    out << "(" << v.X() << ", " << v.Y() << ", " << v.Z() << "; " << v.T() << ")";     out.flush();
}
