[Bug c++/20357] New: Multiply defined assembler symbols for template instantiations

["heinlein at informatik dot uni-ulm dot de" <gcc-bugzilla at gcc dot gnu dot org>]

The following code produces the assembler message: 
"Error: symbol `_ZN1XIXadL_Z1fvEEEC1Ev' is already defined". 
If the declaration of f in main is omitted, everything is fine. 
 
typedef void (*Func) (); 
template <Func f> 
struct X { X () {} }; 
void f () {} 
X<f> x; 
int main () { 
  void f (); 
  X<f> x; 
}
