   * CWE: 190 Integer Overflow
   * BadSource: max Set data to the max value for int
   * 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: 44 Data/control flow: data passed as an argument from one function to a function in the same source file called via a function pointer
