The `(uint16 * uint16)` operation triggers the following ubsan error: ``` runtime error: signed integer overflow: 65535 * 65535 cannot be represented in type 'int' ``` According to this [SO post](https://stackoverflow.com/questions/24371868/why-must-a-short-be-converted-to-an-int-before-arithmetic-operations-in-c-and-c) we might need a special case for uint16 (or perhaps it depends on the arch) multiplication. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
