Invariant for loop [anonymous_loop_0] is
  if serr = True then s1 = False /\ s0 = False /\ 43 <= c0
  else if s1 = True then s0 = False /\ 0 <= c0 /\ c0 <= 42
       else s0 = True /\ c0 = 0
Domains for loop [anonymous_loop_0] are
  c0 = [0;+oo[; s0 = top; s1 = top; serr = top
The generated invariant does not imply { c0 <= 43 }
