           Summary: ICE with "struct C {} C;" and inheritance
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Keywords: ice-on-valid-code, monitored
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: reichelt at gcc dot gnu dot org
                CC: gcc-bugs at gcc dot gnu dot org

The following valid code snippet crashes every gcc release since gcc 2.95.x
as well as mainline:

==============================
struct A
{
    struct C {} C;
};

struct B : A
{
    struct C {} C;
};
==============================

With mainline for example I get:

bug.cc:9: internal compiler error: in pop_binding, at cp/decl.c:1138
Please submit a full bug report, [etc.]

The bug looks similar to PR 9777, but isn't quite the same.
