VPP crashes when invoking an `lcp create` on a tagged sub-interface with an IP address.

VPP was started with

./vpp -c /etc/vpp/startup.conf

CLI Commands:

The last line is responsible for the fault. Commands were issued through VPPCTL. The netns namespace was already existing on the linux host.

set interface state TenGigabitEthernet2/0/1 up
ip table add 1001
create sub-interfaces TenGigabitEthernet2/0/1 1001 dot1q 1001 exact-match
set interface ip table TenGigabitEthernet2/0/1.1001 1001
