Template deduction issues with VC++ 2005

I posted this earlier in comp.lang.c++ but was told this could be a
VC++ 2005 compiler bug. Can anyone tell me if this is a known issue?

==========Original Post Follows===========================
I am sure this is going to turn out to be a dumb question but here goes
anyway.
I was trying out the Hello World equivalent of a template program that
determines whether the type passed is a class type. This example is
lifted straight out of C++ Templates by Josuttis et al. However I
can't get it to compile with VC++ 2005. Here is what I tried:

template<typename T>
class IsClassT
{
private:
    typedef char One;
    typedef struct { char a[2]; } Two;
    template<typename C> static One test(int C::*);
    template<typename C> static Two test(...);
public:
    enum { Yes = sizeof(IsClassT<T>::test<T>(0)) == 1 };
    enum { No = !Yes };

};

struct Idiot
{

};

int main()
{
    if (IsClassT<Idiot>::Yes)
        std::cout << "Hurray!\n";

    return 0;

}

The compiler complains:

1>c:\work\workarea\allpurposeconsoleapp\allpurposeconsoleapp\allpurposeconsoleapp.cpp(510)
: error C2783: 'IsClassT<T>::Two IsClassT<T>::test(...)' : could not

I thought promoting a zero integral constant to a pointer is preferred
over ellipsis?

thanks!
