------- Additional Comments From reichelt@gcc.gnu.org  2003-05-27 00:29 -------
A reduced testcase is the following:

--------------------------------------------
template <typename> struct A
{
    template <typename> struct B {};
};

struct C
{
    typedef X Y;
    A<int>::B<Y> b;
};
--------------------------------------------

The error message from gcc 3.3 is:

PR10706.cc:8: error: ISO C++ forbids declaration of `X' with no type
PR10706.cc:8: error: parse error before `;' token
PR10706.cc:9: error: `Y' was not declared in this scope
PR10706.cc:9: error: template argument 1 is invalid
PR10706.cc:9: internal compiler error: tree check: expected tree_vec, have 
   error_mark in mangle_class_name_for_template, at cp/pt.c:3845
Please submit a full bug report, [etc.]

The code crashes every release since gcc 2.95.x.
Since it is not a regression and the problem is fixed on mainline,
I close the PR.
