Yes, kernel no longer crashes and sshd (without fix in PR/38396)
fails (properly?):

>> sshd[491]: error: mm_send_fd: sendmsg(7): Invalid argument
>> sshd[491]: fatal: mm_answer_pty: send fds failed
>> sshd[491]: error: close(s->ptymaster/0): Bad file descriptor
>> sshd[554]: error: mm_receive_fd: recvmsg: expected received 1 got 0
>> sshd[554]: fatal: mm_pty_allocate: receive fds failed

Should also this be pulled up to netbsd-4?
