            Reporter: Zoltan Haindrich



{code:sql}
create table t (a varchar(10));

insert into t values('bee'),('xxx');

-- select  t0.v,t1.v from
select       assert_true(t0.v = t1.v) from
        (select hash(a) as v from t where a='bee') as t0 
join    (select hash(a) as v from t where a='bee' or a='xbee') as t1 on (true);
{code}

the assertion fails because: {{97410 != 127201}}
