--------------------------------------------------------------
Thanks to [~gopalv] for coming up with a very small test case and code fix:
{noformat}
drop table if exists foo;
create temporary table foo (x int, y int) stored as orc;
insert into foo values(1,1),(2,NULL),(3,1);
select x, IF(x > 0,y,0) from foo order by x;
{noformat}
