The attached setup script / pcap capture causes vpp to crash instantly. This is derived from Codenomicom ip4 test #27927, which features an ipv4 source address of 0.0.0.0.
In turn: vnet_buffer(p0)->ip.adj_index[VLIB_TX] = -1, which causes the wheels to fall off.
You'll need to modify setup.pg to point wherever bug.pcap lands.
