Because they are short on actual bugs to be found by their tooling
and attempt to inflate the sound/noise rate; therefore, every time
when overflow _IS_ handled correctly, it must have been an accident -
we couldn't have possibly done the analysis correctly.  And if somebody
insists that they _are_ capable of basic math, they must be dishonest.
So... "unintentional" it's going to be.

Al, more than slightly annoyed by that aspect of the entire thing...
