>Description:
Consider the following code snippet:

----------------------------snip here---------------------------------
template <typename> struct A {};

template <typename> struct B
{
    typedef A<typename X::Y> C;
};
----------------------------snip here---------------------------------

Compiling this with mainline I get:

PR8582B.cc:5: error: `X' is not a class-name or namespace-name
PR8582B.cc:5: internal compiler error: Segmentation fault
Please submit a full bug report, [etc.]

With gcc 3.2.3 or 3.3 branch I get:

PR8582B.cc:5: error: `X' is not a class or namespace
PR8582B.cc:5: error: `Y' is not a class or namespace
PR8582B.cc:5: error: `X' fails to be a typedef or built in type
PR8582B.cc:5: error: ISO C++ forbids declaration of `type name' with no type

So we have an ice-on-illegal-code (error recovery problem) on mainline
which is a regression w.r.t. 3.3 branch.
