A number of updates for issues found by static code analysis, etc. have been fixed since 4.2.1 was released.  Without any sort of reproducer case for this there's no way I can know whether it's been addressed or not so I'm closing this.  Feel free to add a comment if you still see it with Git HEAD and I can re-open.
