[Bug c++/28107] New: Incomplete type in struct added to global namespace

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

For the following invalid code snippet

==================
struct A
{
    union B b;
};

struct B;
==================

the C++ frontend generates the following error message:

bug.cc:3: error: field 'b' has incomplete type
bug.cc:6: error: 'struct' tag used in naming 'union B'

While the first line is OK, the second one is not.
Apparently, union B is added to the global namespace.
IMHO it should be placed into A.
