Hi!

logged in today into my openbsd box(ver 3.5),
typed last -10 and out follows

-bash-2.05b$ last -10
date      {                                 Fri Sep 24 14:41
date      |                                 Fri Sep 24 14:41

where these lines could come?
box is as is, have not done any tweaking etc
