--- Comment #11 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
It is always good if you're testing on x86_64 to test such tests with
make check-gcc
RUNTESTFLAGS="--target_board=unix\{-m32/-mno-mmx/-mno-sse,-m32/-msse2,-m64\}
dg.exp='pr105109.c c23-tag-enum-*.c'"
or similar, that allows testing both 64-bit and 32-bit compilation and for the
latter both the variants with vector support and without (e.g. in case test
needs -Wno-psabi).
I certainly see
+FAIL: gcc.dg/c23-tag-enum-6.c (test for errors, line 10)
+FAIL: gcc.dg/c23-tag-enum-6.c (test for errors, line 13)
+FAIL: gcc.dg/c23-tag-enum-7.c (test for excess errors)
+FAIL: gcc.dg/pr115109.c (test for excess errors)
on i686-linux and not on x86_64-linux and the above make check would show it
immediately, even before trying to bootstrap/regtest the patch.
