with that BT I looked at the src and it became obvious, the check:
https://cgit.freedesktop.org/realmd/adcli/commit/?id=213116ea8a16a10f4def750d92095c250b51def7
needs to move into the else part holding
_adcli_info ("Received NetLogon info from: %s", disco->host_name);
as disco ptr can be NULL otherwise
