Description Nathan Ridge CLA 2011-01-21 17:01:10 EST 
For the following code:

#include <iostream>
using namespace std;

template <typename T>
void g()
{
    cout << "one\n";
}

template <typename T, typename U>
void g()  // ERROR HERE
{
    cout << "two\n";
}

int main()
{
    g<int>();
    g<int, int>();
    return 0;
}

The parser gives the error: "Invalid redefinition of g".

The code compiles fine with gcc and produces the output

one
two

as expected.
