The following invalid code snippet triggers an ICE since GCC 3.0:
==================================
struct A
{
struct { static int i; };
void foo() { i; }
};
==================================
bug.cc:3: error: 'int A::<anonymous struct>::i' invalid; an anonymous union can
only have non-static data members
bug.cc: In member function 'void A::foo()':
bug.cc:4: internal compiler error: Segmentation fault
Please submit a full bug report, [etc.]

This patch works for me but I don't know if it is correct, it mirrors other
places which uses currently_open_derived_class but we now get a bogus error
message with this patch:
