<pre>The current trunk version of clang in C++11 mode reports an error for the
second static assert in the following sample (but not for the equivalent first
one) and crashes for the T3 typedef.
int main() {
typedef int __attribute__((__aligned__(1))) T1; // no error
static_assert(alignof(T1) == 1, "wrong alignment");
constexpr int A = 1;
using T2 = int __attribute__((__aligned__(A)));
static_assert(alignof(T2) == 1, "wrong alignment"); // error
typedef int __attribute__((__aligned__(A))) T3; // crash
static_assert(alignof(T3) == 1, "wrong alignment");
}</pre>
