Oh well, so much for that theory.

Usually, segfaults in sshd are actually in a PAM module, but they can be
rather hard to track down.  Could you try running sshd on a separate port
with the -d flag so that you can get a trace on the server of where the
segfault happens?  You may be able to capture a core dump that way so that
you can get a backtrace and see where it's exploding.
