-----------------------------------------

Verified fixed in: 1.1.0

#Thu Jun 18 16:36:49 EDT 2015
git.commit.id.abbrev=a027f69

Test cases:
{code}
select sum(a2) over(partition by a2 order by a2), count(*) over(partition by a2,b2,c2)  from
t2 order by 1,2;
select sum(a2) over(partition by a2 order by a2), count(*) over()  from t2 order by 1,2;
select sum(a2) over(partition by a2 order by a2), count(*) over(order by a2)  from t2 order
by 1,2; 
select sum(a2) over(partition by a2 order by a2), count(*) over(partition by a2 order by b2)
 from t2 order by 1,2;
select sum(a2) over(partition by a2 order by a2), count(*) over(partition by b2 order by b2)
 from t2 order by 1,2;
select sum(a2) over(partition by a2 order by a2), sum(*) over(partition by b2 order by b2)
 from t2 order by 1,2; 

-- mix window clause with over clause (different) 
select
        avg(a1) over w1,
        sum(a1) over w1,
        row_number() over (order by b1)
from    t1
window w1 as (partition by c1);

-- Should not be disabled
select
        avg(a1) over w1,
        sum(a1) over w1,
        sum(a1) over (partition by b1)
from    t1
window w1 as (partition by b1); 
{code}
