A couple of comments: this is almost certainly a bug in Matlab or one of
the libraries it uses -- it should not crash like this. Also, this is an
X-related issue, and thus belongs on the cygwin-xfree list, not the main
one -- please direct all follow-ups there (should happen automatically
with the current Reply-To).
That said, you may find
<http://x.cygwin.com/docs/faq/cygwin-x-faq.html#q-ssh-no-x11forwarding>
helpful for finding a workaround for your problem.

If there's any real truth it's that the entire multidimensional infinity
