Hi Dave,
Because I didn't subscribe the list, so please CC me when reply:) My
colleague help to forward your reply to me, so I decide to reply
directly in order to keep this mail in the thread other than new a thread.

Sorry, I am to new dump/crash area.

I am using kdump to create the vmcore. Actually, I did solve this issue
by add "nokaslr" to kernel parameter when I used the built-in crash of
Fedora. But when turn to the compiled version of my own, that solution
don't work. here is the output of `crash -d8`:
$ sudo ./crash -d8 /var/crash/127.0.0.1-2017-11-22-18\:21\:42/vmcore
