>Description:
The following code causes an ICE when compiled with the new parser:

---------------------snip here-------------------
template <typename T> struct A
{
    void foo() { using T::X; }
};
---------------------snip here-------------------

The error message is:

bug.cc: In member function `void A<T>::foo()':
bug.cc:3: internal compiler error: in validate_nonmember_using_decl, at 
   cp/decl2.c:4152
Please submit a full bug report, [etc.]

Since we get a sensible error message with the 3.2/3.3 branch,
this is a regression.
