The following (IMHO valid) code snippet triggers an ICE since GCC 4.1.0:

==================================
struct A
{
  int i;
};

extern "C" struct B : A
{
  A::i;
};
==================================

bug.cc:7: internal compiler error: tree check: expected tree that contains
'decl with visibility' structure, have 'field_decl'  in decl_linkage, at
cp/tree.c:2225
Please submit a full bug report, [etc.]
