[Bug c++/35023] New: [4.3 regression] ICE with parameter pack in variable declaration

["reichelt at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

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.]
