<pre>Compiling the following code with clang++ -c test.cpp -std=c++11 fails with the
missleading error message
test.cpp:14:14: error: dependent using declaration resolved to type without
'typename' using Base::B;
template <class T>
class A {};
template <class T>
class B {
public:
B(){};
};
template <class T>
class C : public B<A<T>> {
public:
using Base = B<A<T>>;
using Base::B; // <-- Error here
};
static const C<int> c{};
When writing one of the following, equivalent statements instead of "using
Base::B" the code compiles:
using Base::Base
using B<A<T>>::Base
The error does also not occur if A is not a templated class. The code compiles
fine with gcc 4.9. I've posted a question at stackoverflow regarding this
problem at <a href="http://stackoverflow.com/q/27954940/2188211">http://stackoverflow.com/q/27954940/2188211</a></pre>
