```sql
SELECT order_id, CONCAT('sum:', sum(cnt)) FROM (
SELECT order_id, user_id, COUNT(1) AS cnt FROM t_order GROUP BY
order_id, user_id
) a GROUP BY order_id;
```
### Actual behavior
```
ERROR 1815 (HY000): Internal error: Error while preparing statement [SELECT
order_id, CONCAT('sum:', sum(cnt)) FROM ( SELECT order_id, user_id,
COUNT(1) AS cnt FROM t_order GROUP BY order_id, user_id ) a GROUP BY order_id]
