--- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
A simple tail recusion case:
```
struct Slice {
const char* data;
unsigned long size;
~Slice();
};
Slice get_s_impl();
Slice get_s(bool t)
{
if (!t)
return get_s(!t);
return {};
}
```
Which is also missed with `-O2 -fno-inline` (note -fno-inline is needed as GCC
knows how to handle inlining here).
