Please don't top post ... reordered.

VC6 is pretty strange, I agree. In particular, it doesn't handle functions with non-type template parameters well. The following code should demonstrate the problem. (Hopefully I'm remembering the problem correctly -- I don't have VC6 installed on this machine.)

template<int I> void foo() { std::cout << I << '\n'; }

int main() { foo<1>(); foo<2>(); return 0; }

If you must use VC6, avoid non-type template parameters for function templates.

This returns in both cases the same value. Is there a way around this problem at all?

Try using integer wrappers. The MPL ones should do the trick: template<typename Int> void foo() { std::cout << Int::value << '\n'; } int main() { foo >(); foo >(); return 0; } The original problem was using bools as a non-type template parameter, so the fix would be to use mpl::true_ and mpl::false_. -- Eric Niebler Boost Consulting www.boost-consulting.com
