[Bug c++/21903] Default argument of template function causes a compile-time error

In private mail, I got another testcase that is even weirder: 
--------------------------- 
struct O { 
    template<typename T> struct B { 
        void set (T, bool=true); 
    }; 
 
    struct D : public B<int> {}; 
}; 
 
void x () 
{ 
  O::B<int> d; 
  d.set(1); 
} 
---------------------------- 
Note that now we allocate an object of type O::B<int>, and get the same 
error as before. The type O::D isn't used anywhere; however, if we comment 
out the line in which it is declared, the test suddenly starts to compile. 
 
What does confuse me, to be honest, is that icc shows the same behavior... 
 
Nathan, Giovanni?
