   * BadSource:  Allocate memory without using sizeof(int)
   * GoodSource: Allocate memory using sizeof(int)
   * Sink: memmove
   *    BadSink : Copy array to data using memmove()
   * Flow Variant: 22 Control flow: Flow controlled by value of a global variable. Sink functions are in a separate file from sources.
