// Illegal access to private member not detected, program compiles silently.
// bug found in:
// g++ (GCC) 4.1.2 20080704 (Red Hat 4.1.2-44)
// g++ (Ubuntu 4.3.3-5ubuntu4) 4.3.3
#include <iostream>

class A {
enum { value=1 };       // private
};

template <int i>        // bug appears only if B is a template
struct B {
 enum { value=A::value }; // <- silently access private member
};

int main() {
  std::cout << B<1>::value << std::endl;
