Reproduces the bug

Compile attached file with
clang++ -std=c++11 -stdlib=libc++ TestFunctional.cpp -o TestFunctional

The relevant function:

void Capture(std::function<void (CDispatchTypeTag *)> const &_Function)
{
  //auto Function = _Function; // Uncomment this and it works
  auto fTest
    = [_Function]()
    {
      _Function(nullptr);
    }
  ;
}

The destructor and copy constructor is not called the correct number of times
unless the line above is uncommented.</pre>
