Annotation is not a valid proof of correctness.
Annotation is not valid for all loop-free paths from entry of procedure __VERIFIER_assert to check that a call to reach_error is unreachable at line 14. One counterexample starts in \old(cond)=0 and ends in \old(cond)=0, cond=0.
Annotation is not valid for all loop-free paths from loop head at line 20 to check that invariant of correctness witness holds at line 20. One counterexample starts in x=-7 and ends in x=1.
Annotation is valid for all loop-free paths from entry of procedure main to check that invariant of correctness witness holds at line 20.
