Sub-goal Assertion of goal main'vc.
Prover result is: Unknown (sat).
The program does not comply to the verification goal, for example during the
  following execution:

    zero = 0
  Line 14:
    Constant one initialization
    one = 1

Prover result is: Unknown (sat).
The program does not comply to the verification goal, or the contracts of
