Sorry for the repost, but there was no answer to this (http://tinyurl.com/3yba8) and I'm still not sure if it is a compiler or a boost defect. Which f should be called here? void f(const char*) { std::cout << "function called!" << std::endl; } template <typename T> void f(const T&) { std::cout << "function template called!" << std::endl; } int main() { char buf[10] = { 0 }; f(buf); } In my opinion, it should be the function template (which whould also mean that EDG works correctly and VC 7.1 not) as "f(char[10])" is no exact match for the function. However, this would also mean that there is a defect in boost.test (see link above). br, Stefan *********************************** Stefan Slapeta Wien/Vienna, Austria http://www.slapeta.com
