Daniel Sanders ef8761fd3b Fix non-determinism in Reassociate caused by address coincidences ... Summary: Between building the pair map and querying it there are a few places that erase and create Values. It's rare but the address of these newly created Values is occasionally the same as a just-erased Value that we already have in the pair map. These coincidences should be accounted for to avoid non-determinism. Thanks to Roman Tereshin for the test case.
