--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
First of all, this test isn't present on 8 branch at all, only trunk.
And, this exact testcase uses -fno-builtin and thus tests the library, so if it
fails, likely your libc is buggy.
Which exact subtest fails for you?
E.g. replace
#define CHECK(x) if (!(x)) __builtin_abort ()
with
#define CHECK(x) if (!(x)) __builtin_printf ("bug at %d %s\n", __LINE__, #x);
and see what it prints?
