Not a bug. There is nothing wrong with your code from the
compiler's point of view, so it cannot help. Any help must
come from the linker, and should be reported as a bug to
the creators of your linker.

Hi,
I'm not certain that this should be considered as a bug. However it is the only case that I now, where when calling a virtual member function that is declared as abstract (=0),
the linker (and not the compiler) produces the error.
This can be confusing, when a big number of nested classes is involved.
Hope I helped !
>How-To-Repeat:
struct A
{
virtual int f() = 0;
};
struct B : A
{
int f()
{
return A::f();
};
};
int main()
{
B t;
};
>Fix:
The linker message is informative enough
