--- Comment #5 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
IOW, this should be accepted in C++23 but isn't (clang++ accepts in C++23):

struct AutoPtr {
    AutoPtr() =3D default;
    AutoPtr(AutoPtr&) {}
};

template<class T> auto f(T p, int) -> decltype(throw p, 1) =3D delete;
template<class T> void f(T p, long);

void
g ()
{
  f (AutoPtr (), 42);
