Reduced test case:

module m
  implicit none
  type t
    character :: str(11)
  end type t

  interface char
    module procedure char_auto
  end interface char

contains
  pure function char_auto (string) result (char_string)
    type(t), intent(in) :: string
    character(LEN=size(string%str)) :: char_string
    integer :: i_char
    forall(i_char = 1:size(string%str))
       char_string(i_char:i_char) = string%str(i_char)
    end forall
  end function char_auto

  elemental subroutine split_CH (string, set)
    type(t), intent(inout)         :: string
    character(LEN=*), intent(in)                :: set
    integer :: i
    do i = 1, min(len(set),size(string%str))
      string%str(i) = set(i:i)
    end do
  end subroutine split_CH
end module m

use m
type(t) :: mdt, mdt2(2),setdt
mdt%str = ['H', 'e', 'l', 'l', 'o', ' ', 'W','o', 'r', 'l', 'd']
mdt2 = [ mdt, mdt ]
setdt%str = ['F', 'o', 'r', 't', 'r', 'a', 'n','R', 'u', 'l', 'z']

call split_CH(mdt2, char(setdt))
print '(11a)', mdt2(1)%str
print '(11a)', mdt2(2)%str
if (any (mdt2(1)%str /= setdt%str)) call abort ()
if (any (mdt2(2)%str /= setdt%str)) call abort ()
end
