```
select /*+ aggOptions(is_partitioned_by_group_by_keys = 'true') */
AirlineID, count(*)
from airlineStats
group by 1
order by 2
```
causes error b/c directly the `order by` operation cannot know count(*) is a
non-nullable result column thus the isNullLast check in query context
compilation will fail (b/c V2 engine doesn't carry the `*` argument over to the
QueryContext thus causes isNullLast check accessing operand position out of
bound:
```
