--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Works for me on aarch64-linux-gnu with:
GNU C++14 (GCC) version 7.0.0 20160717 (experimental)
(aarch64-unknown-linux-gnu)

Maybe provide a preprocessed source which fails.

For me it expands to:
# 6 "t.c" 3 4
       do { unsigned int __i; fd_set *__arr = (
# 6 "t.c"
       &set
# 6 "t.c" 3 4
       ); for (__i = 0; __i < sizeof (fd_set) / sizeof (__fd_mask); ++__i)
((__arr)->fds_bits)[__i] = 0; } while (0)
# 6 "t.c"
                    ;
