OK there's some warnings in there that we should look at after the
release. (Actually someone sent in a fix for those "type-punned
pointer" warnings but it looks like that slipped through the cracks.)

Does this error happen consistently? Some of the tests are inherently
racy, and this is one of them. There are "sleep" commands sprinkled in
strategic places but sometimes they're not enough.

Fortunately this is a relatively easy test to simulate:

run "/path/to/sshd -oLoginGraceTime=10s -oLogLevel=debug3-De -p 4242"

from another shell, connect to localhost port 4242 and type
"SSH-2.0-fake" followed by a newline.

Wait and see if the connection drops after 10 seconds or so, which it
should.

If/when it does, try logging in with ssh: "ssh -p 4242 localhost" and
see what happens.

Thanks.

Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
