Hi, Damjan
Thanks for your help, and the backtrace from gdb is below (a file with same
content is attached for better format). I use the commit
ce4083ce48958d9d3956e8317445a5552780af1a (“dpdk: offloads cleanup”) to get
these info. The previous one commit 3b7ef512f190a506f62af53536b586b4800f66c1
("misc: fix the uninitialization error") does not cause the error.
Thread 1 "vpp_main" received signal SIGSEGV, Segmentation fault.
