   * BadSource:  Allocate using malloc() and set data pointer to a small buffer
   * GoodSource: Allocate using malloc() and set data pointer to a large buffer
   * Sinks: loop
   *    BadSink : Copy twoints array to data using a loop
   * Flow Variant: 66 Data flow: data passed in an array from one function to another in different source files
