   * CWE: 122 Heap Based Buffer Overflow
   * BadSource:  Allocate memory for a string, but do not allocate space for NULL terminator
   * GoodSource: Allocate enough memory for a string and the NULL terminator
   * Sink: loop
   *    BadSink : Copy array to data using a loop
   * Flow Variant: 32 Data flow using two pointers to the same value within the same function
