// More similar cases. Static members also may be accessed
#include <iostream>
class A {
enum { value=1 }; // private
static const int ci=2;
static int fi() { return 3; }
};
template <int i> // bug appears only if B is a template
struct B {
enum { value=A::value }; // <- silently access private member
// enum { v2=A::ci }; // this error is detected @ any instantiation
static const int v3=A::value; // not detected
static const int v4=A::ci; // not detected
static int f5() { return A::value; } // not detected
static int f6() { return A::ci; } // detected only if f6() accessed
static int f7() { return A::fi(); } // detected only if f7() accessed,
reported twice
};
int main() {
std::cout << B<1>::value << B<1>::v3 << B<1>::v4 << B<1>::f5()
// << B<1>::f6() // error will be detected
// << B<1>::f7() // error will be detected, and reported TWICE
<< std::endl;
return 0;
