Example:

    int a_global = 0;
    void function1() {
      a_global += 1;
      if (a_global > 1)    // + 1 use reference
        a_global = 0;
    }
    void function2() {
      a_global -= 1;
      a_global -= 1;
      if (a_global < 0)    // + 1 use reference
        a_global = 0;
      if (a_global > 10)   //     duplicate does not count
        a_global = 10;
    }
                           // CountUsesUnique = 2
