 A shorter (IMHO legal) testcase is the following:
 
 =============================================================================
 template <typename T> struct A
 {
     typedef int X;
 };
 
 template <typename T> struct B
 {
     typename A<T>::X x;
 };
 
 template <typename T> struct C
 {
     void foo(int);
     B<A<T>*> b;
 };
 
 template <typename T> struct D
 {
     enum { e };
     void bar() { C<T*>::foo(e); }
 };
 =============================================================================
 
 It compiles fine with gcc 2.95.3 - 3.3 branch, but crashes with
 gcc 3.4-20030116. The message is:
 
 PR9388.cc: In instantiation of `B<A<T*>*>':
 PR9388.cc:14:   instantiated from `C<T*>'
 PR9388.cc:20:   instantiated from here
 PR9388.cc:8: error: `B<T>::x' has incomplete type
 PR9388.cc:8: internal compiler error: in cxx_incomplete_type_diagnostic, at 
    cp/typeck2.c:278
