Thanks for the heads up.  If any of these are recent regressions
(either the false negatives or the false positives) it would be
helpful to isolate them to a few representative test cases.
The warning itself hasn't changed much in GCC 12 but regressions
in it could be due to the jump threading changes that it tends to
be sensitive to.
