You can submit a bug report against BIND at bind9-bugs at -- if 
you do, please include as much information as possible about the system
you're running on, how you configured the built ("named -V" will tell
you this), and your named.conf ("named-checkconf -px" dumps a copy of
your configuration with key secrets omitted).

If the problem's in the samba DLZ module, I probably won't be able to
help you, but if it's in the dlopen driver, perhaps I can.
