 Hi,
 here is a shortened version of the code-snippet in question:
 
 template<int SIZE>
   class B
   {
     public:
       class P {};
   };
 
 template<int SIZE>
   void the_bug(B<SIZE>::P p)
 {}
 
 void test()
 {
 //    the_bug<10>(B<10>::P());  // line X, compiles
     the_bug(B<10>::P());      // line Y
 }
 
 It comes down to the question, whether the compiler should be able to
 deduce the template-argument SIZE of the_bug from a function-argument,
 in which SIZE is a template-argument of an *enclosing* class.
 (Note, that if one explicitly calls the_bug<10>, as in line X, the code
 compiles fine. )
 
 After browsing through Section 18.4.2 of the C++-Standard, I believe
 that compilers do not need to be able to perform this deduction, so the
 described problem is probably not a bug in gcc.
 
 Best regards,
 Joerg Peters
