Hmm, I thought I have fixed this bug. But seems that we have other path that
trigger this panic. Actually, it is easy to workaround the panic, but I want
more tests to find the root cause of panic. I'll try to reproduce the panic
later. If you have a reliable reproduce process, please let me know.

Thanks,
