--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Note here is a C++11 testcase which shows the problem and shows it is a
regression:
 template<typename T> struct sk_sp {
    template<typename U> sk_sp(sk_sp<U> const &);
    ~sk_sp() {}
};
struct SkPicture {};
struct Wrapped: SkPicture {
    Wrapped(SkPicture const &);
};
struct S {
    sk_sp<SkPicture const> x;
    Wrapped y;
};
sk_sp<SkPicture> ref(SkPicture *);
void f(SkPicture * x, SkPicture const & y) {
    new S{ref(x), y};
}
