v4-0001-Check-for-overflow-when-decoding-an-interval.patch (text/x-patch) patch v4-0001

Actually found an additional overflow issue in
DecodeInterval. I've updated the patch with the
fix. Specifically it prevents trying to negate a field
if it equals INT_MIN. Let me know if this is best
put into another patch.
