R1340 fixes the problem, R1341 is a slight cosmetic fix (uses a #define rather than the raw value), would prefer to include this so it matches upstream
R1342 adds some extra checks that haven't been proven to cause a problem but are good, you may not apply this bu certainly at a minimum R1340 is required to fix this bug.
