Sub-goal Postcondition of goal f'vc.
Prover result is: Unknown (sat) (689 steps).
The program does not comply to the verification goal, for example during the
  following execution:
File int.mlw:
  Line 13:
    Constant zero initialization
    zero = 0
  Line 14:
    Constant one initialization
    one = 1
File if_decision_branch.mlw:
  Line 8:
    Constant path_selector initialization
    (giant-step) execution of unimplemented function with args:
    result = {sel_path= false}
    path_selector = {sel_path= false}
  Line 18:
    a = 5
    a = 5
    Execution of main function `f` with env:
      path_selector = {sel_path= false}
      a = 5
      zero = 0
      one = 1
  Line 22:
    Normal execution of function `(=)` with args:
      x = 5
      y = 1
    Normal execution of function `sel_path` with args:

    Normal execution of function `sel_path` with args:

    Property failure at postcondition of `f` with:
