openssh unix dev - Feb 2014 - openssh-6.5p1 on Solaris 10 - segmentation fault

I just installed 'openssh-6.5p1' on a Solaris 10 system, and when
attempting to 'ssh' anywhere as anybody from the 'root' account,
I get a segmentation fault.

Debug output as 'root':

'ssh' does appear to work as a regular user, but all the Cisco SSH 
connections hang again; haven't had time to investigate what combinations
of ciphers and key exchange methods work with the latest version, if any.
With the new version it hangs at:

debug1: SSH2_MSG_KEX_DH_GEX_REQUEST(1024<3072<8192) sent
debug1: expecting SSH2_MSG_KEX_DH_GEX_GROUP

Version 6.4 shows:

debug1: SSH2_MSG_KEX_DH_GEX_REQUEST(1024<1024<8192) sent
debug1: expecting SSH2_MSG_KEX_DH_GEX_GROUP
debug1: SSH2_MSG_KEX_DH_GEX_INIT sent
debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY

Any ideas?

Thanks,
Mike
