An updated testcase that compiles without errors on 4.4.0:

========== 8< ==========
template < typename > struct A ;
template < typename T , typename = A < T > > struct B
{ } ;
template < class W , class > struct D
{
        typedef W X ;
        A < X * > a ;
} ;
template < class Y > struct E
{
        B < Y * > b ;
} ;
E < int > e ;
========== >8 ==========
