--- Comment #7 from Martin Liška <marxin at gcc dot gnu.org> ---
Minimal test-case:
template <typename> class A {
template <typename U> A<U> &&operator=(A<U> &&)&;
template <typename U> A<U> &&operator=(A<U> &&)&&;
}
template A < int >&&A < int >::operator= ( A &&
Same as the origin, it's obviously an invalid code.
