--- Comment #1 from Damien Miller <djm at mindrot.org> ---
None of the packet layer functions work after the connection has been
freed.

I think the main problem here is that sshd is calling
audit_event(SSH_CONNECTION_ABANDON) and you seem to have patched
audit-linux.c to try to handle that case. You should handle it
separately, e.g. calling it early or skipping the ssh_remote_ipaddr()
call.
