Annotation is not a valid proof of correctness.
Annotation is not valid for all loop-free paths from entry of procedure fibo2 to exit of procedure fibo2. One counterexample starts in \old(n)=6 and ends in \old(n)=6, \result=1, n=6.
Annotation is not valid for all loop-free paths from entry of procedure fibo1 to exit of procedure fibo1. One counterexample starts in \old(n)=2 and ends in \old(n)=2, \result=2, n=2.
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 41.
