Oh well now that you mention it and I look past things, I see we’re using INT_MAX, but should probably use INT32_MAX. https://github.com/theory/pg-semver/blob/87cc30cbe80aa3992a4af6f19a35a9441111a86c/src/semver.c#L145-L149 And also that the destination value we’re storing it in is an int parts[], not int32 parts[]. Which we do so we can parse numbers up to int size. But to Fetter’s point, we’re not properly handling something greater than int (usually int64, presumably). Not sure what changes are required to improve memory safety over and above using INT32_MAX instead of INT_MAX. Thanks, Daavid
