--- 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() {
test4();
return 0;
}

Another simple case that fails (even without instantiation) is:
templatesize_type size, size_type alignment
struct aligned_storage
{
using type = struct { alignas(alignment) unsigned char data[size]; };
};
from http://en.cppreference.com/w/cpp/types/aligned_storage
The error is:
error: requested alignment is not an integer constant
using type = struct { alignas(alignment) unsigned char data[size]; };

Note the testcase is missing an instantiation, like just fooint f;, required to show the problem.
