 Reproduced with 3.2.1 and 3.3:
 
 test.c: In instantiation of `C<A<<anonymous> >::B>':
 test.c:3:   instantiated from here
 test.c:2: internal compiler error: Segmentation fault
 
 2.95 also ICEs, but in a different fashion:
 
 test.c:3: Internal compiler error 980422.
 
 I do not know whether this is valid C++ or not.
