thanks for your reply.

i found that no errors will be reported if i delete the line `bar(A::i)', so is
that a bug?

in fact the original code is like:
template <int>
class A
{
    static const int i = -1;
}

template <>
class A<0>
{
    static const int i = 0;
}

//and some other specializations...

and i don't want to write lots of "const int A<N>::i"...
