        * trans-array.c (structure_alloc_comps): On deallocation of
        class components, reset the vptr to the declared type vtable
        and reset the _len field of unlimited polymorphic components.
        *trans-expr.c (gfc_find_and_cut_at_last_class_ref): Bail out on
        allocatable component references to the right of part reference
        with non-zero rank and return NULL.
        (gfc_reset_vptr): Simplify this function by using the function
        gfc_get_vptr_from_expr. Return if the vptr is NULL_TREE.
        (gfc_reset_len): If gfc_find_and_cut_at_last_class_ref returns
        NULL return.
