[Bug c++/21895] New: [wrong-code] template class member function with array typedef arguement behaves erroneously

["leventyilmaz at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Here is a sample code that generates the problem (tried to reduce it as much as
possible):

#include<iostream>
template<class T>
class Bar 
{
public:
  void foo(T a) { std::cout << a << std::endl; }
};

int main()
{
  typedef int arr[3];
  arr sz={0,1,2}; 
  std::cout << sz << std::endl; // prints address of sz[0]
  Bar<arr>().foo(sz);  // prints another address!!
  return 0;
}

Note:
Everything works fine and this erroneous behaviour is NOT observed if
- foo is a non-member template function: 
     template<class T> void foo(T);
- foo is a member function with non-generic arguement:
     typedef int arr[3];
     template<class T> void Bar<T>::foo(arr a);
- foo is exact same as the code above (member func with generic arguement) but
the  arguement is a reference rather that pass by value 
     template<class T> void Bar<T>::foo(T& a);
