Dirk,
	write your main() as:

int main() {

    try {

        ... your stuff here ...

    } catch (std::exception& e) {
        std::cout << e.what() << std::endl;
    }

}

and the segfault will go away. What happens is that the current  
implementation of binomial engines do not provide greeks, and QuantLib  
signals it by throwing an exception when delta() is called.

HTH,
