The following code compiles fine with MSVC 2010.

#include <cstddef>
#include <boost/static_assert.hpp>

template<class T = int, std::size_t N = 3>
class C {
public:
    C() {}
    C(const T& i0) {
        BOOST_STATIC_ASSERT(N == 1);
        m_data[0] = i0;
    }
private:
    T m_data[N];
};

int main() {
    C<> c;
}

Can you provide a minimal *complete* test
case that fails?
