I've just had a bug in one of our private dissectors which meant
that the handle passed to call_dissector was null. This seemed to give
varying behavior - on some Windows installations it hit wireshark's
in-built exception handling, and displayed that the dissector had an
error (correct), but on some installations it just crashed wireshark
(not helpful). I _think_ the difference was whether MSVC was installed
or not, but on a sample of only 3 machines.
Should call_dissector include explicit null handle checks, and if so,
should it:-
a) g_assert - the simple patch attached
b) fallback to doing a data decode (as disabled protocols do)
c) try to invoke the wireshark exception handling for the packet
Or is the correct answer none of the above - the exception handler
should already cope ?
