You're either passing ~0 to vlib_get_node - or causing the infra to do so -
which can't possibly work:
vlib_get_node (i=4294967295, vm=0x7ffff79aa2a0 <vlib_global_main>)
You didn't send a full backtrace so there's nothing more I can do to help.

Subject: [vpp-dev] new next_node caused Segmentation fault
Hi all,
I tried to add a new next node to the node "ip4_local_node",
but which caused a segmentation fault, is there something I have missed?
typedef enum
{
IP_LOCAL_NEXT_DROP,
IP_LOCAL_NEXT_PUNT,
IP_LOCAL_NEXT_UDP_LOOKUP,
IP_LOCAL_NEXT_ICMP,
IP_LOCAL_NEXT_CAPWAP,
IP_LOCAL_N_NEXT,
} ip_local_next_t;
VLIB_REGISTER_NODE (ip4_local_node) =
{
.function = ip4_local,
.name = "ip4-local",
.vector_size = sizeof (u32),
.format_trace = format_ip4_forward_next_trace,
.n_next_nodes = IP_LOCAL_N_NEXT,
.next_nodes =
{
[IP_LOCAL_NEXT_DROP] = "error-drop",
[IP_LOCAL_NEXT_PUNT] = "error-punt",
[IP_LOCAL_NEXT_UDP_LOOKUP] = "ip4-udp-lookup",
[IP_LOCAL_NEXT_ICMP] = "ip4-icmp-input",
[IP_LOCAL_NEXT_CAPWAP] = "ethernet-input",
},
