--- Comment #2 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
Present from 4.8.2 up to trunk (5.0 r218188). Compiling the test in comment 0
with 4.7.3 gives

  class(*), intent(in) :: s
          1
Fatal Error: Unlimited polymorphism at (1) not yet supported

I don't get an ICE, but the error

Error: Entity 's' at (1) has a deferred type parameter and requires either the
pointer or allocatable attribute
