Bug on the RawString method of the Layer class #6

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?

        RawLayer raw_header;
        raw_header.SetPayload("SomePayload");
        raw_header.RawString();

What is the expected output? What do you see instead?

The program should print the hex string of the raw header, instead a 
segmentation fault happens. 

Program received signal SIGSEGV, Segmentation fault.
