openssh unix dev - Jun 2001 - Output of last command is strange on Solaris 2.6/8 (OpenSSH 2.9p2)

Hi.

OS: Solaris 2.6 and 8
OpenSSH: 2.9p2

I found a bug.
Output of last command becomes strange in case of "UseLogin yes"
in sshd_config.
# Two entries are output with one time of login.

strange case:
 % last
 fuga      pts/3        bar.foo.co.jp    Thu Jun 21 12:45 - 20:02  (07:16)
 fuga      pts/3        bar.foo.co.jp    Thu Jan  1 09:00 - 12:45 (11494+03:45)
 hoge      pts/2        foo.bar.co.jp    Thu Jun 21 11:12 - 15:30  (04:17)
 hoge      pts/2        foo.bar.co.jp    Thu Jan  1 09:00 - 11:12 (11494+02:12)
 ....


When comment on it with wtmp_write_entry and wtmpx_write_entry of
login_utmp_only function, last output an usual entry.

 % last
 fuga      pts/3        bar.foo.co.jp    Thu Jun 21 12:45 - 20:02  (07:16)
 hoge      pts/2        foo.bar.co.jp    Thu Jun 21 11:12 - 15:30  (04:17)
 ...

If there is a right method of this case, please teach it.
