[NETSTAT] crashes when called with -abnop

netstat crashes during parsing cmdline options when it is called like this

netstat -abnop

Expected result of MS netstat on XPSP3:
MS_netstat_on_XPSP3_does_neither_show_UDP_nor_TCP_connections_then.PNG
but it doesn't crash

Please notice that our netstat also does not crash when called like that

netstat -abnop udp

netstat -abnop tcp

So the problem is the -p parameter parsing if we don't append a protocol name to it.
