    Annotation is not a valid proof of correctness.
Annotation is not valid for all loop-free paths from loop head at line 38 to check that procedure precondition always holds at line 38. One counterexample starts in \old(counter)=0, A=0, b=0, B=0, counter=2147483647, q=0, r=0 and ends in \old(counter)=0, A=0, B=0, b=0, counter=-2147483648, q=0, r=0.
