Resolution: Duplicate
> TestDecimalFuzz hits DCHECK math-functions-ir.cc "Check failed lhs > 0 && rhs
> > 0"

>
> Key: IMPALA-7461
> URL: https://issues.apache.org/jira/browse/IMPALA-7461
> Project: IMPALA
> Issue Type: Bug
> Components: Backend
> Affects Versions: Impala 3.1.0
> Reporter: Joe McDonnell
> Assignee: Joe McDonnell
> Priority: Blocker
> Labels: broken-build
>
> Several builds have been failing with an impalad hitting this DCHECK:
> {code:java}
> auto MultiplicationOverflows = [](ActualType lhs, ActualType rhs) {
> DCHECK(lhs > 0 && rhs > 0); <----- HERE
> using ActualType = decltype(lhs);
> return BitUtil::CountLeadingZeros(lhs) + BitUtil::CountLeadingZeros(rhs) <=
> BitUtil::UnsignedWidth<ActualType>() + 1;
> };
> {code}
> This happens during the TestDecimalFuzz test:
> {noformat}
> I0817 10:50:44.950784 10364 Frontend.java:1024] Analyzing query: select
> width_bucket(cast(-10.0 as decimal(8,6)), cast(-10.0 as decimal(3,1)),
> cast(6490371073.16853453566312041152511 as decimal(36,25)), 26386065)
> F0817 10:50:44.952258 10364 math-functions-ir.cc:516] Check failed: lhs > 0
> && rhs > 0{noformat}
> It looks like a regression due to the fix for IMPALA-7412.
