[Click] clicky assert

[rootkit85 at yahoo.it]

Hi,

I have some clicky crahes, so I trimmed my configuration to a minimal test case.

Here is the configuration:

d :: Discard;

Idle -> SimpleQueue -> d;
Idle -> Classifier(-) -> d;

and the crash:

$ clicky crash.click
clicky: processingt.hh:48: int ProcessingT::pidx(const PortT&, bool)
const: Assertion `port.router() == _router' failed.
Aborted (core dumped)

I know that the configuration is invalid even if it worked with older
versions of click:

$ click crash.click
‘Classifier at 5 :: Classifier’ push output 0 connected to ‘d :: Discard’
pull input 0
Router could not be initialized!

but I think that clicky shouldn't crash.

Best Regards,
Matteo Croce
