--- Comment #6 from janus at gcc dot gnu.org ---
Reduced test case for the ICE:

  print *, associated(return_pointer()) ! ICE
contains
  function return_pointer()
    class(*), pointer :: return_pointer(:)
  end function 
end

ICEs with 4.8, 4.9, trunk. Rejected by 4.7, because class(*) is not supported.
