Is something like this possible? (I'm leaning towards not, but I just thought I'd make sure...) The code: With compiler errors for it:
class Base {
};
class Derived : public Base {
};
int main(int argc, char* argv[]) {
boost::shared_ptr<Base> b(new Derived);
boost::shared_ptr<Derived> d(b); // line 25
}
