--- Comment #1 from G. Steinmetz <gscfq@t-online.de> ---

With a non-parameterized type instead :


$ cat zz1.f90
program p
   type t
      integer :: n
      integer, pointer :: a(:)
   end type
   type(t) :: z
   print *, z
end


$ gfortran-11-20200531 -c zz1.f90
zz1.f90:7:13:

    7 |    print *, z
      |             1
Error: Data transfer element at (1) cannot have POINTER components unless it is
