--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed, reduced testcase:
```
const char **
add_string(int *restrict n, const char *strings[restrict *n])
{
  strings = __builtin_realloc(strings, *n);
  if (!strings)
    return 0;
  return strings;
}
```

Note if we had `int n` instead of a pointer, then there would be no warning.
