   * CWE: 122 Heap Based Buffer Overflow
   * BadSource:  Initialize the source buffer using the size of a pointer
   * GoodSource: Initialize the source buffer using the size of the DataElementType
   * Sinks:
   *    BadSink : Print then free data
   * Flow Variant: 81 Data flow: data passed in a parameter to an virtual method called via a reference
