Unfortunately I am not setup to build a debug version.  But I have
tested on a new machine and can report that it happens if user running
the sshd service does not have write permission to the /var/log/sshd.log
file.  In this case it actually seems easy to reproduce.

OK.  The pipe thing makes sense.  But supplying the password does not
work either:
  $ net use '\\other\f$' MyPassword1
  System error 1909 has occurred.
