--- Comment #2 from Mikael Morin <mikael at gcc dot gnu.org> ---
The generated finalization wrapper has code doing
  deallocate(ptr2%classes(:)%class_var)
where ptr2 is a pointer of type list_t to be finalized.
This is missing scalarization, a correct code would do instead:
  do i=1,size(ptr2)
    ptr3 => ptr2%classes(i)
    deallocate (ptr3%class_var)
  end do
