--------------------------------------
I have filed CALCITE-7729 with an additional linq4j bug which hides exceptions.
> Review safety of checked arithmetic operators
> ---------------------------------------------
>
> Key: CALCITE-7725
> URL: https://issues.apache.org/jira/browse/CALCITE-7725
> Project: Calcite
> Issue Type: Task
> Reporter: Ruben Q L
> Assignee: Mihai Budiu
> Priority: Major
> Fix For: 1.43.0
>
>
> At the moment, some checked arithmetic operators (CHECKED_PLUS,
> CHECKED_MINUS, CHECKED_TIMES, CHECKED_MINUS_PREFIX) are part of the
> {{safeOps}} set in {{RexSimplify#SafeRexVisitor}}, i.e. they are considered
> "safe" by {{RexSimplify#isSafeExpression}} .
> To be reviewed if these operations should be considered actually "safe",
> since they can throw at runtime (in case of overflow), similarly to e.g. a
> division by zero, which is considered "unsafe".
