   * @description
   * CWE: 190 Integer Overflow
   * BadSource: connect_socket Read data using a connect socket (client side)
   * GoodSource: Set data to a small, non-zero number (two)
   * Sinks: square
   *    GoodSink: Ensure there will not be an overflow before squaring data
   *    BadSink : Square data, which can lead to overflow
   * Flow Variant: 68 Data flow: data passed as a global variable from one function to another in different source files
   *
