Hi, In FDIO vpp 21.01, while testing TCP traffic observing a seg fault resulting in vpp abort. Generated the core dump and ran gdb on it. bt was pointing to 'dpdk_plugin' in vpp
$ gdb vpp <core_dump> warning: Unable to find matching inferior's thread library, thread debugging will not be available. Core was generated by `vpp -c /etc/vpp/startup.conf'.

But still we are getting above warning. In FDIO vpp 21.01 version, can dpdk_plugin be built with debug symbols ? Any flag or additional code changes needed ? Can you please help on this regard.
