Description :

The following example shows that the private field A::i can be accessed in an annotation. In my opinion the access rules in annotations should be the same as for code.

struct A { private:

int i;

public:

explicit A(int k) : i(k) {}

/*@
  assigns \nothing;
  ensures \result == i;
*/
int get() const
{
    return i;
}

};

int foo(const A& a) { int b = a.get(); //@ assert b == a.i; // Frama-Clang allows access to private field of A

// a.i cannot be accessed here because it is private
// this is recognized by Frama-Clang
// int c = a.i;

return b;

}
