--- Comment #2 from G. Steinmetz <gscfq@t-online.de> ---

Slightly different :


$ cat z7.f90
module m
   type t(a, :, *)
   end type
end


$ cat z7s.f90
subroutine s
   type t(a, :, *)
   end type
end


$ cat z8.f90
module m
   type t(*, a, :)
   end type
end


$ cat z8s.f90
subroutine s
   type t(*, a, :)
   end type
end
