[Bug c++/13349] New: [3.3 regression] Infinite memory usage for invalid code

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

The following invalid code snippet triggers an infinite loop in gcc 3.3.x:

======================================
namespace A {}
namespace B { using namespace A; }
namespace A { using namespace B; }

A::X x;
======================================

Previous versions and mainline issue a correct error message.

This is a redux of the second bug in PR 11282.
