--- Comment #1 from anlauf at gcc dot gnu.org ---
Interesting.  Reduced testcase:

program pr113471
  implicit none
  type :: t
     integer, dimension(2) :: c1 =3D 0
  end type t
  integer :: i, ii
  type(t) :: cc(3)
  print *, "size(cc), size (cc(1)%c1) =3D", size(cc), size (cc(1)%c1)
  do i =3D 1, size(cc)
     print *, i, ":", cc(i)% c1
     ii =3D pick (cc(i)% c1)
  end do
contains
  integer function pick (c)
    integer :: c(:)
    pick =3D 0
  end
end
