The following valid code snippet triggers an ICE since GCC 3.4.0:

===========================================================
template<typename T> struct A
{
  T a, __attribute((unused)) b;
};
===========================================================

bug.cc:3: internal compiler error: in layout_type, at stor-layout.c:1864
Please submit a full bug report, [etc.]

Without the variable 'a' I get a warning (which is missing in the case above):
bug.cc:3: warning: 'unused' attribute ignored
