--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Reduced testcase (removes the templates, also now able to compile as C):
typedef const int T1;
typedef const int T2;
void std_equal(T1* a1, T1* a2, T2* b1);
void f() {
    int a[3] = {1, 2, 3};
    T1* x    = a;
    T2* y    = a;
    std_equal(x, x+3, y);
}
