      Description

      According to these declarations:

      class Item_basic_constant :public Item
      {
        table_map used_table_map;
        ...
      };
      ...
      class Item_cache: public Item_basic_constant
      {
      protected:
        Item *example;
        table_map used_table_map;
      ...
      }

      Item_cache has two used_tables_cache, one of which is declared in Item_cache itself, and another one is derived from Item_basic_constant.

      It's very likely that the second declaration is not really necessary.
