Annotation is not a valid proof of correctness.
Annotation is not valid for all loop-free paths from entry of procedure func_to_recursive_line_13_to_18_0 to check that procedure precondition always holds at line 52. One counterexample starts in \old(s)={4:3} and ends in \old(s)={4:3}, s={4:3}.
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 25.
Annotation is valid for all loop-free paths from entry of procedure __VERIFIER_assert to exit of procedure __VERIFIER_assert.
