This is because some of the test cases are made to mess with the python hashing function.

Wrap your ints in this class before hashing to fix it:

from random import getrandbits
class Wrp(int):
    RANDOM = getrandbits(32)
    def __init__(self, x):
    def __hash__(self):
        return super(Wrp, self).__hash__() ^ self.RANDOM
