Comment (by AlexanderThiemann):

 I've tried to consistently reproduce the bug but it only happens in maybe
 5-10% of all runs (see also
 https://github.com/agrafix/Spock/issues/44#issuecomment-134899484 ). Since
 removing the minBound..maxBound calls the bug seems to have gone away. Is
 there any non deterministic behavior in Enums/Bounded?
