Re: non-const reference to tem****ary derived from pure virtual Base

Hi,

i striped it down further to:

class Derived  {
public:
   Derived(int i)      {};
};

class User {
public:
   void useBase(Derived& b) {};
};

int main() {
   User u;
   u.useBase(Derived(1));
}

I think it's just a "feature" to prevent writing code with surprising 
results....
