--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Well, the return is missing here ... if the frontend would emit

int f (void)
{
  return D.1234; // uninitialized
}

then it would work.  The C++ FE emits __builtin_unreachable traps () instead.
I think this should be addressed in the frontend.
