--- Comment #4 from Martin Sebor <msebor at gcc dot gnu.org> ---
Still fails on trunk:
$ cat u.cpp && /home/msebor/build/gcc-trunk-svn/gcc/xgcc
-B/home/msebor/build/gcc-trunk-svn/gcc -Wall -Wextra -Wpedantic -std=c++11
-xc++ u.cpp
struct alignas(32) alignas(8) S { char d[8]; };
static_assert(alignof(S) == 32, "");
u.cpp:2:1: error: static assertion failed
 static_assert(alignof(S) == 32, "");
