--- Comment #10 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
This might be slightly smaller, (removes c++20 specific stuff) (I can't test it
with the failing case):
```
int a;
void b();
struct e {
int ab;
int d() { return ab; }
};
struct f {
e g;
auto d() { return g.d(); }
};
template <typename h> struct i : h {
f j;
template <typename ac> int ad(ac) {
unsigned char k = j.d();
a = __builtin_ia32_bzhi_di(1, k);
b();
return a;
}
};
struct l {
void af();
};
struct n {
void ap() {
at.af();
at.ad(1);
}
i<l> at;
};
void f() {
n b;
b.ap();
}
```
