[Bug c++/39211] New: Function pass by reference problem, accepts parameters (int, int) to an (int*, int*) function.

[eakrohn at cs dot uiowa dot edu]

The following code works and it shouldn't.  It only works with passing 2
parameters from what I tested.  If I try swap(int *x) or swap(int *x, int *y,
int *z), it gives an error as expected.  But with 2 parameters it compiles and
runs.  

void swap(int *x, int *y)
{
        int temp;
        temp = *x;
        *x = *y;
        *y = temp;
}

int main()
{
        int x = 10;
        int y = 20;
        std::cout << x << " " << y << endl;
        swap(x,y);  //this compiles, runs and swaps...  it shouldn't
        std::cout << x << " " << y << endl;
}
