   * CWE: 131 Incorrect Calculation of Buffer Size
   * 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: cpy
   *    BadSink : Copy string to data using strcpy()
   * Flow Variant: 15 Control flow: switch(6)
