[Bug c++/28109] New: [4.0/4.1/4.2 regression] ICE with typeid of incomplete type

[reichelt at gcc dot gnu dot org]

The following invalid code snippet causes an ICE since GCC 3.4.0:

=================================
#include <typeinfo>

struct A;

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

bug.cc: In function 'void foo()':
bug.cc:7: error: aggregate 'A a' has incomplete type and cannot be defined
bug.cc:8: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in get_tinfo_decl_dynamic, at cp/rtti.c:238
Please submit a full bug report, [etc.]

Testing a patch.
