--- Comment #3 from Steven Dwy <me at yoplitein.net> ---
With this fix sizeof an address of a string literal is also the length of the
string:
```
const int s1 = sizeof("aa");
_Static_assert(s1 == 3, "");
const int s2 = sizeof(&"aa");
_Static_assert(s2 == sizeof(void*), ""); // fails
```

Additionally, the following invalid code is now accepted:
```
char(**s1)[3] = &(&"aa");
char(***s2)[3] = &(&(&"aa"));
// and so on
```
