   * @description
   * CWE: 190 Integer Overflow
   * BadSource: listen_socket Read data using a listen socket (server side)
   * GoodSource: Set data to a small, non-zero number (two)
   * Sinks: add
   *    GoodSink: Ensure there will not be an overflow before adding 1 to data
   *    BadSink : Add 1 to data, which can cause an overflow
   * Flow Variant: 66 Data flow: data passed in an array from one function to another in different source files
   *
