samba - Apr 2024 - named wont start

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";
    };

versions:

    root at nc1:/etc/bind# named -version
    BIND 9.18.26-1+ubuntu22.04.1+deb.sury.org+1-Ubuntu (Extended Support
    Version) <id:>

OK, this works for myself, but using Samba 4.19.5 and named 9.18.24 on
aarch64.
It looks like something changed, but where.

Does named start if you use the latest Ubuntu package (9.18.18 from
security) with Samba 4.20.0 ?

As far as I am aware, there have been no recent major changes in the
Samba bind9_dlz code.
