           Summary: Internal compiler error
           Product: gcc
           Version: 3.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: dave at boost-consulting dot com
                CC: gcc-bugs at gcc dot gnu dot org

I believe the root of the problem is in passing class templates in the form of 
outer<T>::inner<U> as template template parameters.

OK, here's a reduced testcase (that was tough...):
-------------------------
template <typename> struct W {};

template< template<typename> class F, typename T>
int foo(W< F<T> >);


template<typename T>
struct L  {
    static int const value = sizeof(foo(W<T>()));
    typedef T type;
};


template <typename>
struct Y {
    template <typename> struct X { typedef int type; };
    typedef typename L<X<int> >::type type;
};

template struct Y<int>;
-----------------------------

This crashes all compiles I have, since 2.95. With 3.3 and 3.4 we get:
g/x> /home/bangerth/bin/gcc-3.3*-pre/bin/c++ -c z.cc
z.cc: In instantiation of `L<Y<int>::X<int> >':
