Hi All!

ICE with simple subroutine missing a dummy argument.

subroutine foo(that)
  implicit none
  class(*),  target, intent(in)  :: this
  class(*), pointer, intent(out) :: that

  that => this
  return
end subroutine foo

Tested on:

GNU Fortran (GCC) 11.0.1 20210410 (experimental)
GNU Fortran (GCC) 10.3.1 20210410
GNU Fortran (GCC) 9.3.1 20210410

Thank you very much.

Best regards,
José Rui
