Actually, that example is probably okay. Steven Lionel wrote:

"But reading this I wonder if it's intended to mean actual arguments of derived
type with allocatable components, rather than a regular allocatable array,
since there's no issue of making copies of subcomponents here. Let me discuss
it with my
team here."


However, the following code should be invalid (due to the implicit deallocating
the allocatable component *on the remote image*):

type t
  integer, allocatable :: x
end type t
class(t), allocatable :: x[:]
 call bar(x[1]) ! <<< Wrongly accepted.
! call foo(x[1]) ! OK: Rejected coindexed polymorphic -> polymorphic not
allowed
contains
 subroutine bar(r)
   type(t) :: r
 end
 subroutine foo(r)
   class(t) :: r
 end
end
