This looks like a case where, in minusP, negateP was properly promoting the negation of -9223372036854775808 (Long/MIN_VALUE) to a BigInt, but that promotion didn't propagate to addP. The Ops that got used in addP was ops(-9223372036854775808), not ops(9223372036854775808N).

The attached patch makes sure the BigInt contamination goes all the way through, and adds a few tests verifying the correct behavior.
