----------------------------------------
Summary: Possible overflow in long = int * int
Key: SPARK-23893
URL: https://issues.apache.org/jira/browse/SPARK-23893
Project: Spark
Issue Type: Bug
Components: Spark Core, SQL
Affects Versions: 2.3.0
Reporter: Kazuaki Ishizaki
To perform `int * int` and then to cast to `long` may cause overflow if the MSB
of the multiplication result is `1`. In other words, the result would be
negative due to sign extension.
