With THROW.

However, you should throw an exception only if further dissection of
*anything* in the packet is impossible - other than subsequent PDUs in
the TCP byte stream.

In the case of subsequent PDUs in the TCP byte stream, the NBSS
dissector catches the ReportedBoundsError exception, reports a malformed
packet, and returns so that subsequent PDUs can be dissected.

If you add a new type of exception, it should catch those as well.
