Example #1

        /* goodG2B() - use goodsource and badsink */
        private static void GoodG2B()
        {
            StringBuilder data = CWE476_NULL_Pointer_Dereference__StringBuilder_61b.GoodG2BSource();

            /* POTENTIAL FLAW: null dereference will occur if data is null */
            IO.WriteLine("" + data.Length);
        }

Example #2

        public override void Bad()
        {
            StringBuilder data = CWE476_NULL_Pointer_Dereference__StringBuilder_61b.BadSource();

            /* POTENTIAL FLAW: null dereference will occur if data is null */
            IO.WriteLine("" + data.Length);
