(a*b) product of two fields -> (1337, 'Something broke')

[jdxin0]

Sum works fine when sum one field.

select sum(count) from test where  __time >= "2018-08-15" and __time < "2018-08-16"
sum(count)
214174390

But it brokes when sum the product of two fields.

select sum(count*count2) from test where  __time >= "2018-08-15" and __time < "2018-08-16"
(1337, 'Something broke')

select count*count2 from test where  __time >= "2018-08-15" and __time < "2018-08-16"
(1337, 'Something broke')
