This needs a Fixes tag as well.

Here my records show that I looked at this in 2018 but I probably
ignored it based on that the code was introduced in 2012.  When warnings
are really ancient sometimes I just assume they must be false positives
or someone would have hit it in testing.

Also for really ancient bugs, it's hard to contact the original author
or they have forgotten the details of the code.
