bind-9.9.0 crashed while rndc reload

[Drunkard Zhang]

Last day I tried new bind, and the crash when reloading comes.

The reload command: 'rndc -c etc/rndc.conf reload' or 'killall -HUP
named', the used rndc.conf was generated by 'rndc-confgen -r
/dev/urandom -t /chroot/'. And messages below comes from offline
debug.

And this is a simple debug.

gdb /usr/sbin/named
(gdb) r -u named -c etc/named.conf -t /tmp/dt/chroot/ -g

Run ‘killall -HUP named’ in anaother terminal to reload config.

(gdb) q
A debugging session is active.

	Inferior 1 [process 19895] will be killed.

Quit anyway? (y or n) y

Should I debug with debug symbol enabled?
And I'm also trying to find out which part in my configuration caused the crash.

Glad to hear from you :-)
