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

===================================
struct A
{
  void foo();

  void bar(int i)
  {
    void (*p)() = i ? foo : foo;
  }
};
===================================

bug.cc: In member function 'void A::bar(int)':
bug.cc:7: internal compiler error: in instantiate_type, at cp/class.c:6280
Please submit a full bug report, [etc.]
