The script should keep running.

On a Unix system I'd just use ulimit to disable core dumps and not worry
further about it.  The problem with windows is that it displays a monolog
box whenever an app crashes.  This might be perceived by a user as the
configure script crashing.  Hence printing message stating otherwise
prior to running the test on windows might be in order.
