In the loop head node, references [i21, i20] were interesting.
By SMT, we could prove
((100 <= initial_i20 and 0 <= initial_i21 and 0 <= initial_i1) and (((path1_i24 = (path1_i20 + 1) and path1_i25 = (path1_i21 + 1) and path1_i24 = res_i20 and path1_i25 = res_i21 and path1_i1 = res_i1 and path1_i20 = initial_i20 and path1_i21 = initial_i21 and path1_i1 = initial_i1) and path1_i21 < path1_i20) and ((res_i24 = (res_i20 + 1) and res_i25 = (res_i21 + 1)) and !res_i21 < res_i20)))
to be UNSAT. Consequently, the loop will not terminate.
