Member template internal compiler error

I am getting an Internal Compiler Error in VC++ 6 with the following code.
I'm fairly sure it is well-formed (g++ 3.4.2 compiles it fine). Is there a
workaround available?

#include <iostream>
#include <ostream>

class Foo
{
public:
template <int N>
static void Test()
{
std::cout << N << std::endl;
}
};

int main()
{
Foo::Test<5>(); /* I.C.E. here */
}

Thanks for any help you can provide.

VC++ v6 is notoriously bad with templates. You'll be much better off when
you upgrade to the later compiler (7.1 is currently shipping). For now,
if you can, make this static member non-member but a simple free-standing
function template.

this should work: maybe it's not what you mean to do, but other workarounds
are dangerous in VC6

template <int N>
struct placeholder
{
};

class Foo
{
public:
template <int N>
static void Test(placeholder<N> )
{
std::cout << N << std::endl;
}
};

int main()
{
Foo::Test(placeholder<5>());
return 0;
}
