[Bug c++/33459] New: [4.2/4.3 regression] ICE on reference member in union

["reichelt at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The following invalid testcase triggers an ICE since GCC 4.2.1:

===================================
union A
{
  int &i;
};

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

bug.cc:3: error: 'A::i' may not have reference type 'int&' because it is a
member of a union
bug.cc: In function 'void foo()':
bug.cc:8: internal compiler error: Segmentation fault
Please submit a full bug report, [etc.]
