I do not know if this is valid or invalid code but it still ICEs and it is a regression from 
3.3.3.  I found this while trying to reduce PR 13809.

2002-12-28-trunk (#178).

Oh I thought about this a little and this is definitely invalid code.

Confirmed. The code is invalid: 
---------------------- 
template<typename> struct S {}; 
template<typename A, 
         template <typename> class B = S<A> > struct X{}; 
---------------------- 
The default argument should of course be S, not S<A>. 
 
W.

Here's an even shorter testcase:
