> This (meaningless) statement gives NPE in insane builds and
> assert failure in sane builds:
> {code}
> s.execute("create table t2(x int)");
> s.execute("create table t1(x int)");
> s.execute("insert into t2 values 3,4");
> s.executeUpdate("merge into t1 using t2 on (t1.x=t2.x) " +
> "when not matched then insert values (count(*))");
> {code}
> I see it also applies to other aggregates, e.g. MAX.
> stack trace (insane):
> {code}
