The following invalid code snippet triggers an ICE on mainline:
==================================================
template<int> struct A
{
template<typename...> struct B {};
template<typename...T> struct B<int,T*> {};
};
A<0>::B<int> b;
==================================================
bug.cc:5: error: parameter packs not expanded with `...':
bug.cc:5: note: 'T'
bug.cc:5: error: template parameters not used in partial specialization:
bug.cc:5: error: 'T'
bug.cc:8: internal compiler error: tree check: expected tree_vec, have
error_mark in get_innermost_template_args, at cp/pt.c:514
Please submit a full bug report, [etc.]
The testcase didn't crash before 2007-11-03, so it's probably fallout from

* pt.c (find_parameter_packs_r): If ppd->set_packs_to_error,
set to error_mark_node the outermost POINTER_TYPE to the pack if
it is seen in a POINTER_TYPE.
(push_template_decl_real): If check_for_bare_parameter_packs
fails for function return type, set the return type to
integer_type_node. If check_for_bare_parameter_packs failed
for non-function, return error_mark_node.
