The following valid code snippet triggers an ICE since GCC 4.2.0:

==========================
template<int> struct A
{
  int i : 2;

  void foo()
  {
    typeof(i) j;
  }
};
==========================

bug.cc: In member function 'void A<<anonymous> >::foo()':
bug.cc:7: internal compiler error: Segmentation fault
Please submit a full bug report, [etc.]

Also happens with __decltype instead of typeof (on mainline and 4.3 branch).
