The following invalid code snippet triggers an ICE on mainline since today:
=============================================================
template<typename... T> int foo()
{
T t;
return t;
}
void bar()
{
foo<int>();
}
=============================================================
bug.cc: In function 'int foo()':
bug.cc:3: error: parameter packs not expanded with `...':
bug.cc:3: note: 'T'
bug.cc: In function 'int foo() [with T = int]':
bug.cc:9: instantiated from here
bug.cc:4: internal compiler error: tree check: expected record_type or
union_type or qual_union_type, have template_type_parm in lookup_conversions,
at cp/search.c:2444
Please submit a full bug report, [etc.]

* pt.c (finish_member_template_decl): If the type in a TYPE_DECL
is error_mark_node, return an error early.
(find_parameter_packs_r): Pass the pointer set along to recursive
calls of cp_walk_subtrees; don't try to manage the pointer set
ourselves.
(uses_parameter_packs): Pass the pointer set to cp_walk_tree.
(make_pack_expansion): Ditto.
(check_for_bare_parameter_packs): Ditto. Also, don't bother taking
a second pass through the tree with find_parameter_packs_r; that
second pass no longer does anything.
(push_template_decl_real): If we have an erroneous declaration,
set its type to error_mark_node before returning an error.
