--- Comment #6 from Stephan Tolksdorf <st at quanttec dot com> ---
The following example still fails with the current trunk GCC. Should this bug
be reopened, or should I file a new one?

template <int N>          
void test() {
  constexpr int N2 = N;
  typedef int T alignas(N2);
  // error: requested alignment is not an integer constant
}

int main() {
  test<4>();
  return 0;
}
