>Description:
// --------------------------------------------
template < template <class A> class B> class foo{};

template < class C > class bar
{
   foo<bar> x;
};

bar<int> test;
// ---------------------------------------------

This is invalid according to section 14.6.1 paragraph 2
"Within the scope of a class template specialization or partial specialization, when the
 name of the template is neither qualified nor followed by <, it is equivalent to the name of the 
 template followed by the template-arguments enclosed in <>."

So, in the specialization bar<int> the reference bar is actually bar<int> which does not
match the template template parameter in class foo...
>How-To-Repeat:
// --------------------------------------------
template < template <class A> class B> class foo{};

template < class C > class bar
{
   foo<bar> x;
};

bar<int> test;
// ---------------------------------------------

g++ small.cpp
> > no errors

should issue an error message such as:
"small.cpp", line 5.8: 1540-0716 (S) The template argument "bar<int>" does not match the template parameter "template class B".
"small.cpp", line 8.10: 1540-0700 (I) The previous message was produced while processing "class bar<int>".
