<pre>Trying to compile
template<class T>
struct testclass
{
template<int I>
class inner {};
template<int I>
void f(inner<I> ) {}
};
template <typename T, int I> using inner = testclass<T>::inner<I>;
int main()
{
testclass<bool> test;
test.f(inner<bool,3>());
return 0;
}
I get the following crash:
clang-3.3:
