Ok.
Color me convinced, I never even looked at the two different cases, I thought it was just one issue.
Let's just remove the spurious false positive warning then, in order to re-instate the *actual* warning that right now is disabled entirely due to the unrelated false positives.
Thanks for looking into this. Would you happen to also have a patch that can be applied? Hint hint..
