It's unclear to me what to make of this. We have in the past fixed a
number of these, IIRC, and clearly in theory the risk that the warning
points out does exist. But these warnings appear erratic and
inconsistent. I'm using the same compiler versions but I don't see any
of these warnings. So I don't understand exactly what triggers these.
