Small example to reproduce the issue
Clang 3.8 refuses to provide the member function pointer when the member
function was introduced via a using-declaration and its origin has a dependent
name.
The attached snippet fails to compile with:
member-fn.cpp:11:19: error: cannot create a non-constant pointer to member
function
auto memberfn = &B<Args...>::f;
As a workaround the name of the base class can be used to retrieve the member
function pointer.
The example compiles with Clang 3.7, GCC 5.3/6 and MSVC++ 12.0.</pre>
