> Found by: stack scanning{noformat}
> After some investigation, the following query reproduces the issue on
> historical Impala releases (such as Impala 4.0):
> {noformat}
> select count(*) from (select row_number() OVER (PARTITION BY l_partkey,
> l_suppkey ORDER BY CASE WHEN l_shipmode IN ('MAIL', 'AIR') THEN 1 ELSE 0 END
> DESC) RN FROM tpch.lineitem) c WHERE c.rn = 1;{noformat}
> This issue does not reproduce on the master branch, and we have determined
> that the commit for IMPALA-10961 fixed this issue.
> This Jira tracks adding test cases for this issue.
