The following invalid code snippet triggers an ICE on mainline:
======================================
template<typename ...T> struct A
{
typedef typename T::X Y;
};
A<int> a;
======================================
bug.cc:3: error: parameter packs not expanded with `...':
bug.cc:3: note: 'T'
bug.cc: In instantiation of 'A<int>':
bug.cc:6: instantiated from here
bug.cc:3: internal compiler error: in dependent_type_p, at cp/pt.c:14887
Please submit a full bug report, [etc.]

As you've reviewed Doug's previous variadic templates patches, would you care
to review this one?
Thanks,

* typeck.c (check_return_expr): Pass address of retval to
check_for_bare_parameter_packs.
* class.c (build_base_field): Tolerate bases that have no layout
due to errors.
(end_of_base): Ditto.
* tree.c (canonical_type_variant): Be careful with
ERROR_MARK_NODE.
* cp-tree.h (check_for_bare_parameter_packs): Now accepts a
tree*.
* pt.c (find_parameter_pack_data): Add set_packs_to_error field,
which states whether parameter packs should be replaced with
ERROR_MARK_NODE.
(find_parameter_packs_r): Pass addresses to cp_walk_tree wherever
possible. If set_packs_to_error is set true, replace the parameter
pack with ERROR_MARK_NODE. Manage our own pointer sets.
(uses_parameter_packs): Don't set parameter packs to
ERROR_MARK_NODE.
(check_for_bare_parameter_packs): Now takes a pointer to a tree,
which may be modified (if it is a parameter pack). Instructs
find_parameter_packs_r to replace parameter packs with
ERROR_MARK_NODE (so that they won't cause errors later on).
(process_template_parm): Pass pointer to
check_for_bare_parameter_packs.
(process_partial_specialization): Replace pack expansions before
the end of the template argument list with ERROR_MARK_NODE.
(push_template_decl_real): Pass pointer to
check_for_bare_parameter_packs. Replace parameter packs not at the
end of the template parameter list with ERROR_MARK_NODE.
(convert_template_argument): Be more careful about using DECL_NAME
on only declarations.
(unify): Can't unify against ERROR_MARK_NODE.
* semantics.c (finish_cond): Pass pointer to
check_for_bare_parameter_packs.
(finish_expr_stmt): Ditto.
(finish_for_expr): Ditto.
(finish_switch_cond): Pass pointer to
check_for_bare_parameter_packs, and call it before we put the
condition into the statement.
(finish_mem_initializers): Pass pointer to
check_for_bare_parameter_packs.
(finish_member_declaration): Ditto.
* parser.c (cp_parser_base_clause): Ditto.
