[Bug c++/28053] New: [4.2 regression] ICE deriving from class with invalid bitfield

[reichelt at gcc dot gnu dot org]

The following invalid code snippet causes an ICE on mainline:

============================================
struct X {};

struct A
{
    X x : 2;
};

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

bug.cc:5: error: bit-field 'X A::x' with non-integral type
bug.cc:8: internal compiler error: Segmentation fault
Please submit a full bug report, [etc.]

This is a very recent regression (GCC 4.2.0 20060527 was not affected).
