Seems to be the if (*opt_ptr > 0) in pbuf.c line 1036 (at that moment) to 
avoid that opt_ptr += (*opt_ptr - 1) will loop endless.

In the TCPOPT_TIMESTAMP: part a few lines above there is another opt_ptr += 
(*opt_ptr - 1). Is there a chance to get a loop there, too?

Btw, for my testings at home I´m still using tcpsic and the packets 
generated are all pathological but for me it is the only testing method to 
generate random packets for stressing the hashes of ntop (I do not know it 
better, is there another better tool?). An I think ntop should survive in 
spite of it, or?
