Another "funny" thing, trying to use ssh and the ssh-agent on an amd64
computer with the same key:

.eval `ssh-agent -c`
Agent pid 19739

.ssh-add -l
The agent has no identities.

.ssh-add
Enter passphrase for /home/rumrunner/.ssh/id_rsa: 
Error reading response length from authentication socket.
Could not add identity: /home/rumrunner/.ssh/id_rsa

.ssh-add -l
Could not open a connection to your authentication agent.


But still:

.ssh klump
buffer_get_bignum2_ret: bignum is too large
key_from_blob: can't read rsa key
key_read: <dump of key comes here>Enter passphrase for key 
'/home/rumrunner/.ssh/id_rsa': 
Last login: Fri May  9 17:37:27 2014 from elg
<it logs me in at this point>

No newline before the "Enter passphrase..." is how it was displayed.

This is on:

OpenBSD 5.5-current (GENERIC.MP) #126: Mon May 12 22:40:04 MDT 2014
    t...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP
