The C++ frontend rejects the following IMHO valid code snippet since GCC 3.4.0:

==================================================
template<typename T> struct A
{
    template<template<T> class> struct B {};
    template<T> struct C;
    B<C> b;
};

A<int> a;
==================================================

bug.cc: In instantiation of 'A<int>':
bug.cc:8:   instantiated from here
bug.cc:5: error: type/value mismatch at argument 1 in template parameter list
for 'template<class T> template<template<template<T <anonymous> >
class<template-parameter-2-1> > template<class T> template<T <anonymous> >
class<template-parameter-2-1> > struct A<T>::B'
bug.cc:5: error:   expected a template of type 'template<class T> template<T
<anonymous> > class<template-parameter-2-1>', got 'template<int <anonymous> >
struct A<int>::C'

The code compiles if I replace T by int inside A.

------- Comment #1 from pinskia at gcc dot gnu dot org  2006-05-05 15:30 -------
This looks very much related to PR 27403 which also looks very valid.
