JBC Problem based on JBC Program:

package simple.complInterv3;

public class ComplInterv3 {

	public static void loop(int i) {
		while (i != 0) {
			if (i > 5) {
				i++;
			} else {
				if (i < -5) {

In the loop head node, references [i13] were interesting.
By SMT, we could prove
((0 <= initial_i13 and 0 <= initial_i14) and (((path1_i13 = path1_i24 and path1_i24 = path1_i29 and path1_i31 = (path1_i29 + 1) and path1_i31 = res_i13 and path1_i14 = res_i14 and path1_i13 = initial_i13 and path1_i14 = initial_i14) and (path1_i24 > 0 and T and path1_i29 > 5)) and ((res_i13 = res_i24 and res_i24 = res_i29 and res_i31 = (res_i29 + 1)) and !(res_i24 > 0 and T and res_i29 > 5))))
to be UNSAT. Consequently, the loop will not terminate.
