Description of problem:

[18:03:50 pal@underdark ~/tmp/1]$ cat a.cpp
#include <utility>

class A { };

static void g ( A && ) { }

template < class T > class B {
public:
 void f ( ) {
  A a;
  g ( std :: move ( a ) );
 }
};
=================
[18:04:13 pal@underdark ~/tmp/1]$ LANG=C g++ -std=c++0x  -pedantic  -c a.cpp 
a.cpp: In member function 'void B<T>::f()':
a.cpp:11:25: error: invalid initialization of reference of type 'A&&' from
expression of type 'std::remove_reference<A&>::type'
a.cpp:5:13: error: in passing argument 1 of 'void g(A&&)'
=================
error can be fixed by removing -pedantic or by commenting out /*template <
class T > */
