   * CWE: 369 Divide by Zero
   * BadSource: listen_socket Read data using a listen socket (server side)
   * GoodSource: Non-zero
   * Sinks: divide
   *    GoodSink: Check for zero before dividing
   *    BadSink : Divide a constant by data
   * Flow Variant: 63 Data flow: pointer to data passed from one function to another in different source files
