<pre>The following code does not compile:
#include <iostream>
#include <memory>
struct Shared : public std::enable_shared_from_this<Shared>{
};
struct Container : virtual public Shared{
};
struct List : private Container, virtual public Shared {
};
int main(int argc, char** argv){
auto c = std::make_shared<List>();
return 0;
}
The error is:
