Here is a java program (since -fwrapv is turned on by default for java 
front-end unlike the C front-end 
since it is undefined in C and defined in java):
class t
{
  public static void main(String as[])
  {
    int a;
    a = Integer.MAX_VALUE;
    if ((a < 0) || (a + 1 < 0))  {
      System.out.println("Hello");
    }
  }
}
