The following code will cause an access violation error.

T delegate() lazier(T)(lazy T arg){
        bool once = true;
        T value;
        return {
                if(once){
                        once = false;
                        value = arg;
                }
                return value;
        };
}

void main(){
        auto l = lazier(rand());
        writeln(l()); // Access violation
}
