In general, it is not expected that every Bug Finder result must be fixed. My recommendation would be to review the defect using a status such as "No Action Planned" and add a comment to the effect that "13 bytes is not worth optimizing to pass by reference unless we encounter performance issues later when calling this function".

I believe there is not currently a way to set a minimum byte threshold (e.g. 16 bytes) for the expensive pass by value checker.
