>Description:
When compiling the following code I get an ICE:

----------------------------snip here-------------------
template <class T> struct A { typedef int X; };
template <class T> struct B { typedef A<T> Y; void f (Y::X); };
template <class T, class T1, class T2, class T3> struct C : public B<T> { void g (Y::X); };
template class B<int>;
----------------------------snip here-------------------

bug.cpp:2: warning: `typename A<T>::X' is implicitly a typename
bug.cpp:2: warning: implicit typename is deprecated, please see the 
   documentation for details
bug.cpp:3: warning: `typename C<T, T1, T2, T3>::Y::X' is implicitly a typename
bug.cpp:3: warning: implicit typename is deprecated, please see the 
   documentation for details
bug.cpp: In instantiation of `B<int>':
bug.cpp:4:   instantiated from here
bug.cpp:2: internal error: Segmentation fault
Please submit a full bug report, [etc.]

It's a regression from 2.95.2 where the code compiled
without error. With 3.0.x the warnings disappear.

The ICE vanishes if I replace "Y::X" by "typename Y::X".
So it's actually an ice-on-deprecated-code.

The problem is the same as the reduced testcase in PR 3649.
The original testcase compiles fine now, so that PR 3649
was closed.
