<div>
<pre>The code is as follow:
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;
}
clang++ rejects it with an error message:
error: requested alignment is dependent but declaration is not dependent
typedef int T alignas(N2);
^ ~~
The code comes from a gcc bug report:
<a href="https://gcc.gnu.org/bugzilla/show_bug.cgi?id=56871">https://gcc.gnu.org/bugzilla/show_bug.cgi?id=56871</a>
A previous version of g++ also rejects the code, but it is fixed.
Would you please check whether it indicates a bug in clang?</pre>
