--- Comment #7 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The testcase from PR 93415 shows this can produce wrong code too:
template <bool B>
void f (int);
template <bool B = true>
void f (int) {}

template <bool B = true>
void f (char) { __builtin_abort (); }

int main ()
{
    f (0);
    return 0;
}
