   * 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
   * Sinks: memcpy
   *    BadSink : Copy string to data using memcpy()
   * Flow Variant: 44 Data/control flow: data passed as an argument from one function to a function in the same source file called via a function pointer
