   * 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
   * Sinks: memmove
   *    BadSink : Copy string to data using memmove()
   * Flow Variant: 31 Data flow using a copy of data within the same function
