研究方向
The bug involves the error message when using `INET ATON` with `DIV 1`. The expected error should include the function name `inet aton(35)` but instead shows raw values. Look for the code that constructs the error message for unsigned integer overflow, likely in the `expression` package. Check files like `expression/builtin string.go` or `expression/evaluator.go`. The maintainer @XuHuaiyu can provide further hints.
