template<typename> class TP1 {};

template<template<typename> class A>
struct B {
    template<typename T> struct TP2 : public A<T> {};
    };

template<template<typename> class TP3, typename T>
void    F(const TP3<T>&) {}

int main() {
    B<TP1>::TP2<int> b;
    F(b);
    }


gets you:

~/ootbc/members/src$ c++ foo.cc
foo.cc: In function `int main()':
foo.cc:13: error: no matching function for call to `F(B<TP1>::TP2<int>&)'

Note that simplifying to :

struct B {
    template<typename> class TP2 {};
    };

template<template<typename> class TP3, typename T>
void    F(const TP3<T>&) {}

int main() {
    B::TP2<int> b;
    F(b);
    }

does work OK.

This is already fixed in 4.0. In previous versions, one can have a little 
fun if the compiler is configured with checking enabled: 
 
g/x> /home/bangerth/bin/gcc-2.95.3/bin/c++ -c x.cc 
x.cc: In function `int main()': 
x.cc:13: `' cannot be `restrict'-qualified 
x.cc:13: confused by earlier errors, bailing out 
 
g/x> /home/bangerth/bin/gcc-3.2.3/bin/c++ -c x.cc 
x.cc: In function `int main()': 
x.cc:13: no matching function for call to `F(B<TP1>::TP2<int>&)' 
 
g/x> /home/bangerth/bin/gcc-3.3*/bin/c++ -c x.cc 
x.cc: In function `int main()':

   tree_vec) in cp_type_quals, at cp/typeck.c:6567

Er - aren't the "known to fail" and "known to work" reversed?
