In the loop head node, references [i8] were interesting.
By SMT, we could prove
((0 <= initial_i8 and 0 <= initial_i9) and (((path1_i8 = path1_i21 and path1_i23 = (path1_i21 + 1) and path1_i23 = res_i8 and path1_i9 = res_i9 and path1_i8 = initial_i8 and path1_i9 = initial_i9) and path1_i21 > 0) and ((res_i8 = res_i21 and res_i23 = (res_i21 + 1)) and !res_i21 > 0)))
to be UNSAT. Consequently, the loop will not terminate.
