broken on Catalina 10.15.3?

Mar 11 16:55:18 inguz com.apple.xpc.launchd[1] (com.openssh.sshd.---]): Service exited with abnormal code: 255

I can't find any other logs. The update from 10.14 removed authenticator from pam.d/sshd\. When I put it back, it causes sshd to crash. I pulled master from github and recompiled: no change.

any ideas? where can I get more detailed logs?

examples/demo runs fine
