Not really, but I can give you an example.
Line counts for each of the two "break" statements within
_bt_keep_natts_fast() are exactly the same. I don't think that this
because we actually hit each break exactly the same number of times
(90,236 times). I think that we see this because the same instruction
is associated with both break statements in the loop. All of the
examples I've noticed are a bit like that. Not a huge problem, but
less useful than the alternative.
