[Samba] named wont start

[Peter Carlson]

Not sure if this library is provided by samba team or isc, but I can no 
longer start my named service if I connect it with samba. brief history: 
I am having problems with named hanging, isc says step1 is to upgrade to 
the latest bind.  As soon as I upgrade to latest bind, it wont start.  
Now the first step is to figure out which mailing list to talk to

  syslog:

    Apr 30 07:43:02 nc1 named[27557]: Loading 'AD DNS Zone' using driver
    dlopen
    Apr 30 07:43:02 nc1 named[27557]: free(): invalid pointer
    Apr 30 07:43:03 nc1 systemd[1]: named.service: Main process exited,
    code=killed, status=6/ABRT

if I comment out the include it works

    include "/var/lib/samba/bind-dns/named.conf";

named.conf is:

    dlz "AD DNS Zone" {
         # For BIND 9.18.x
          database "dlopen
    /usr/lib/x86_64-linux-gnu/samba/bind9/dlz_bind9_18.so";
    };
