--- Comment #1 from Sam James <sjames at gcc dot gnu.org> ---
stdlib.h:46 for me is:
```
__fortify_function __attribute_overloadable__ __wur char *
__NTH (realpath (const char *__restrict __name,
                 __fortify_clang_overload_arg (char *, __restrict,
__resolved)))
#if defined _LIBC_LIMITS_H_ && defined PATH_MAX
     __fortify_clang_warning_only_if_bos_lt (PATH_MAX, __resolved,
                                             "second argument of realpath must
be "
                                             "either NULL or at least PATH_MAX
"
                                             "bytes long buffer")
#endif
{
  size_t sz = __glibc_objsize (__resolved);

[...]
```

so 'sz' conflicts at least.
