   * CWE: 197 Numeric Truncation Error
   * BadSource: listen_socket Read data using a listen socket (server side)
   * GoodSource: Less than CHAR_MAX
   * Sink: to_char
   *    BadSink : Convert data to a char
   * Flow Variant: 51 Data flow: data passed as an argument from one function to another in different source files
