It depends what you consider a false positive.  I imagine it's 100% accurate,
but it doesn't always indicate a bug, sometimes it warns about code that
behaves exactly as intended.

If it's enabled then the manual should be updated to show one way to unhide the
virtual

        struct B: public A {
          using A::f;
          void f(int);
        };
