----------------------------------
Summary: Query with width_bucket() crashes with Check failed: lhs > 0 && rhs > 0
Key: IMPALA-7459
URL: https://issues.apache.org/jira/browse/IMPALA-7459
Project: IMPALA
Issue Type: Bug
Components: Backend
Affects Versions: Impala 3.1.0
Reporter: Michael Ho
Assignee: Zoltán Borók-Nagy
When running a private exhaustive build, decimal_fuzz_test ran into a case which triggers a DCHECK in MathFunctions::WidthBucketImpl().
{noformat}
select width_bucket(cast(0.3 as decimal(2,2)), cast(0.3 as decimal(5,3)), cast(732.3 as decimal(4,1)), 271287147);
{noformat}
{noformat}
F0817 05:41:55.601862 15604 math-functions-ir.cc:516] Check failed: lhs > 0 && rhs > 0
lhs seems to be 0 in this case.
