openssh unix dev - Feb 2001 - Cannot connect to OpenSSH 2.5.1p1

I've installed today the openssh-2.5.1p1 from RPMS and I cannot use it
with protocol 2. It gives:

And the conenction is dropped. The server says in the log:

Feb 20 17:01:41 server sshd[5525]: fatal: xfree: NULL pointer given as
argument

and that's it. Any ideas? Protocol 1 works OK, so did protocol 2 with
2.3.0.

When I had this same problem I got the latest openssl rpms from RedHat
(I had the ones from OpenSSH.com) and it resolved the problem.  What the
difference is between the two I don't know.  You might give that a try.

I got this last night when trying to login to my work PC from home. The
problem seemed to stem from the fact that I tried to install openssl 0.9.6
rpms at work yesterday (with openssh 2.3.1 (I think) rpms). I've gone back
to
openssl 0.9.5a and am using openssh 2.5.1p1 rpms with no problem. On the
Sun's we have no problem with 0.9.6 and openssh 2.5.1p1 but they are
complied from source. I suspect that compling openssl and openssh both from
source on the linux box will sort it out.
