Why does the following code generate an error ?
This error is described in the gcc manual under the C++ -Woverloaded-virtual
flag. I can't see why gcc can't generate a call to A::f(Y). This exactly
against the behaviour one would expect under the basic principles of
polymorphism.
(gcc 3.4.3).
struct X{};
struct Y{};
struct Z{};
struct A
{
virtual void f(X);
virtual void f(Y);
virtual void f(Z);
};
struct B: public A
{
virtual void f(X);
};
void Test (void)
{
B b;
X x;
Y y;
b.f(x);
b.f(y); // error: no matching function for call to 'B::f(Y&)'
}
