>Description:
The following code is copied from the C++ standard (section 11, clause 5)
class A {
typedef int I;
I f();
friend I g(I);
static I x;
};
A::I A::f() { return 0; }
A::I g(A::I p = A::x);
A::I g(A::I p) { return 0; }
A::I A::x = 0;
It generates an erroneous access error for A::X as shown below:
