   Both ;-) I see no problem in your out-of-class definition of the   
   constructor specialization, so this looks like a compiler defect to me.   
      
   But there is no way to provide explicit template parameters for a   
   constructor, the line   
      
   Test test1(1);   
      
   does not realize this and the code is ill-formed. Providing template   
   parameters for constructors are useless in C++03 (and it impossible to   
   instantiate the constructor). In C++11 there can be used when also a   
   default template argument is provided, e.g. to sfinae-constrain such a   
   constructor.
