    if (length > MaxLength)
        CRASH();

This is a gardening patch. It doesn't need review.
Simply change the "Reviewed by NOBODY (OOPS!)." by something that contains the word "unreviewed" Like "Unreviewed gardening patch" and commit it directly (if you are committer) or ask any comitter to just set the cq+ flag
