Item_func_user doesn't calculate anything in it's val_str() method, just returns saved str_value. Though Item::save_in_field method can destroy str_value, relying on val_str() return. As a result we get the garbage stored in field. We cannot use Item::save_in_field implementation for Item_func_user, reimplement it in simpler way.
