  - 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 entry of procedure sum to exit of procedure sum. One counterexample starts in \old(m)=-1325363200, \old(n)=-1895301117 and ends in \old(m)=-1325363200, \old(n)=-1895301117, \result=0, m=0, n=0.
Annotation is valid for all loop-free paths from entry of procedure main to check that a call to reach_error is unreachable at line 18.
