The issue is caused by a logic error in Item_sum::get_tmp_table_item() method: it resets arguments of the item to point to the result fields during change_ref_to_tmp_fields() call. However, Item_sum arguments must not be modified. It is enough for Item_sum objects to call ancestor's implementation Item::get_tmp_table_item(). This fix is in accordance with MySQL commit 2e3dc09087c24798c90e05163ed3d931f6b93db3 Reviewer: Oleksandr Byelkin <sanja@mariadb.com>
