In the loop head node, references [i105, i104] were interesting.
By SMT, we could prove
((0 <= initial_i104 and 0 <= initial_i105 and 0 <= initial_i1) and ((((path1_i138 = (path1_i104 - path1_i105) and path1_i138 = path1_i142 and path1_i144 = (path1_i105 + 1) and path1_i104 = res_i104 and path1_i144 = res_i105 and path1_i1 = res_i1 and path1_i104 = initial_i104 and path1_i105 = initial_i105 and path1_i1 = initial_i1) and (path1_i105 <= path1_i104 and T and path1_i142 >= 1)) or ((path2_i138 = (path2_i104 - path2_i105) and path2_i138 = path2_i141 and path2_i143 = (path2_i104 + 2) and path2_i145 = (path2_i105 + 1) and path2_i143 = res_i104 and path2_i145 = res_i105 and path2_i1 = res_i1 and path2_i104 = initial_i104 and path2_i105 = initial_i105 and path2_i1 = initial_i1) and (path2_i105 <= path2_i104 and T and path2_i141 < 1))) and (((res_i138 = (res_i104 - res_i105) and res_i138 = res_i142 and res_i144 = (res_i105 + 1)) and !(res_i105 <= res_i104 and T and res_i142 >= 1)) and ((res_i138 = (res_i104 - res_i105) and res_i138 = res_i141 and res_i143 = (res_i104 + 2) and res_i145 = (res_i105 + 1)) and !(res_i105 <= res_i104 and T and res_i141 < 1)))))
to be UNSAT. Consequently, the loop will not terminate.
