Please take a look at: http://www.benzedrine.cx/crashreport.html
There you find information on how to identify the codeline in ip_input.c
that produced the problem. If you can provide this information together with
the trace (you allready included) that is very valueable. Thank you in
advance.
At first glance looks like altq, but can't tell for sure. Somehow the
compiler makes it differently on my box. Check if you can identify the
codeline with the above document, that'll help a lot.
