I can't seem to get it smaller than this: 
------------------------ 
template <typename> struct B { 
    B() throw() {} 
    struct S { }; 
    static int i; 
    typedef unsigned short int dummy; 
}; 
 
template <typename _Tp> 
struct allocator: B<_Tp> { 
    template<typename _Tp1> struct rebind 
    { typedef allocator<_Tp1> other; }; 
}; 
 
template<typename T, typename> 
struct X { 
    typename allocator<T>::template rebind<int>::other i; 
    typedef int* dummy; 
}; 
 
template <class T> class A { 
    typedef typename X<T,allocator<T> >::dummy dummy; 
    template <class TP> class XWrapper; 
}; 
 
 
template <class T> 
template <class TP> struct A<T>::XWrapper<TP *> 
{ 
    XWrapper() {} 
    X<int,allocator<int> > x; 
}; 
 
template class A<int>::XWrapper<int *>; 
--------------------------------- 
 
This crashes both 3.4.x and mainline, but not 3.3.x:
