Sub-goal Assertion of goal f'vc.
Prover result is: Unknown (unknown) (1.24s, 7500000 steps).
The contracts of some function or loop are too weak, for example during the
  following execution:
File int.mlw:
  Line 13:
    Constant zero initialization
    zero = 0
  Line 14:
    Constant one initialization
    one = 1
File func_call1.mlw:
  Line 4:
    Constant z initialization
    (giant-step) execution of unimplemented function with args:
    result = 0
    Normal execution of function `ref` with args:
      contents = 0
    Normal execution of function `ref'mk` with args:
      contents = 0
    z = {contents= 0}
Unknown location:
    _ = ()
File func_call1.mlw:
  Line 13:

    Execution of main function `f` with env:
      z = {contents= 0}
      _ = ()
      zero = 0
      one = 1
  Line 15:
    Giant-step execution of function `g` with args:
      x = 2

    result of `g` = 3
    Normal execution of function `(+)` with args:
      _ = 3
      _ = 3
