su/ssh localhost problems

[Thomas Klausner <wiz%NetBSD.org@localhost>]

Hi!

I've just upgraded to a 20120429 snapshot of NetBSD-amd64 build with clang.

I have trouble becoming root. login on the console works, but when I
login as another user and run "su", <enter> is not accepted -- I can't
get out of the password prompt except by pressing ctrl-c. CTRL-J and
CTRL-M don't work either.
I installed the snapshots as usual, so I don't think it's a permissions problem.
-r-sr-xr-x  1 root  wheel  50429 Apr 30 00:17 /usr/bin/su

I then tried "ssh root@localhost"
# ssh root@localhost
The authenticity of host 'localhost (::1)' can't be established.
ECDSA key fingerprint is 0f:4d:ce:5c:35:c4:98:7e:a9:62:ee:98:d5:fb:68:87.
Are you sure you want to continue connecting (yes/no)? yes??

The '?' are what appear when I press enter.

My terminal is
# echo $TERM
screen

But "export TERM=vt220" or "export TERM=dumb" doesn't change anything.

My previous snapshot was from 20120408.

Anyone else seen this?
 Thomas
