That's a very strange commit to have broken it, but try on master:

git revert 997fbcbc902

If that builds and works, then we have a simple workaround while we ask
Günther and Alexander for help as that is:
 
commit 997fbcbc902d945eb5261ddc6667f830fbcd5931
Author: Günther Deschner <gd at samba.org>
Date:   Sat Feb 13 22:11:52 2021 +0100

    s3-dsgetdcname: return dcinfo also when delivering from the cache.
    
    Guenther
    
    Signed-off-by: Guenther Deschner <gd at samba.org>
    Reviewed-by: Alexander Bokovoy <ab at samba.org>

But do tripple-check, by manually confirming that commit 'git
checkout 997fbcbc902' and the one before 'git checkout 997fbcbc902^'.

Thanks!
