This appears to be a false positive. I filed https://trac.cppcheck.net/ticket/14308 about it.

So unless you get a quick fix for this we can suppress it in the selfcheck (with the actual line as the source is fixed to avoid others to be missed in the future).

#8014 is attempting to fix the false positives.

Looks like that will take a while, so we should probably just suppress the FP for the moment.
