So, that confirms that it is dying in the link() call even though the
location from your stack dump doesn't make sense (not your fault).

Do you have a debugging DLL handy or can I send you one?  If you set a
breakpoint in _link in the cygwin DLL and single step along until it
dies, it should be instructive.

Also does the latest snapshot behave any differently?
