Problem of template

[swh]

Hello.I'm start to write some templates,but I have some questions about
them.

#include <iostream>
using namespace std;

template<typename T> void f(T const& a) {
cout << "Primary" << endl;
}

void f(int const& a) {
cout << "Non-template" << endl;
}

template<> void f(int const& a) {
cout << "Full" << endl;
}

int main() {
f(1.0); // line 1
f(1); // line 2
f<>(1); // line 3
}

The result is:
Primary
Non-template
Non-template

I don't understand the third line in main().I have specified the angle
brackets after the f,
but the resulting call is the Non-template version.Why?

I can only speculate that it's a bug in the compiler. Have you
tried a different compiler?
