[Bug c++/35024] New: [4.3 regression] ICE with parameter pack in nested type

[reichelt at gcc dot gnu dot org]

The following invalid code snippet triggers an ICE on mainline since today:

=============================================================
template<typename... T> int foo()
{
  typename T::X x;
  return x;
}

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:3: internal compiler error: in dependent_type_p, at cp/pt.c:15553
Please submit a full bug report, [etc.]

The code is similar to PR35023, but crashes at a different position.
