  - AnnotationCheckResult: Annotation is not a valid proof of correctness.
    Annotation is not a valid proof of correctness.
Annotation is not valid for all loop-free paths from loop head at line 32 to check that procedure precondition always holds at line 50. One counterexample starts in v=3, x=3, X=1, y=2, Y=1 and ends in v=3, x=3, X=1, xy=6, Y=1, y=2, yx=3.
Annotation is valid for all loop-free paths from loop head at line 32 to check that procedure precondition always holds at line 35.
Annotation is valid for all loop-free paths from entry of procedure assume_abort_if_not to exit of procedure assume_abort_if_not.
Annotation is valid for all loop-free paths from entry of procedure main to loop head at line 32.
Annotation is valid for all loop-free paths from loop head at line 32 to loop head at line 32.
Annotation is valid for all loop-free paths from entry of procedure __VERIFIER_assert to check that a call to reach_error is unreachable at line 15.
Annotation is valid for all loop-free paths from entry of procedure __VERIFIER_assert to exit of procedure __VERIFIER_assert.
