Subject: [Bug debug/22514] New: [4.1 Regression] ICE in force_decl_die with invalid code after error

Take this invalid C++ code, we ICE in force_decl_die when we supply -gdwarf-2:

namespace std {
  template<typename _Alloc> class allocator;
}
namespace boost {
  struct heap_clone_allocator {
  };
  namespace ptr_container_detail {
    template < class Config, class CloneAllocator > struct reversible_ptr_container {
      static const bool allow_null = Config::allow_null;
      template< bool allow_null_values > struct null_clone_allocator {};
    }
  };
}
namespace ptr_container_detail {
  template < class T, class VoidPtrSeq > struct sequence_config {
    typedef typename VoidPtrSeq::allocator_type allocator_type;
  };
}
template < class T, class VoidPtrSeq, class CloneAllocator = heap_clone_allocator > struct 
ptr_sequence_adapter : 
ptr_container_detail::reversible_ptr_container< ptr_container_detail::sequence_config<T,VoidPtrSeq>, 
CloneAllocator >
{
};
 }
namespace std {
  template<typename _Tp, typename _Alloc> struct _List_base {
    struct _List_impl : _Node_Alloc_type {
    };
    _List_impl _M_impl;
  };
  template<typename _Tp, typename _Alloc = std::allocator<_Tp> > struct list : _List_base<_Tp, 
_Alloc> {
    typedef _List_base<_Tp, _Alloc> _Base;
    using _Base::_M_impl;
  };
}
namespace boost {
  template < class T, class CloneAllocator = heap_clone_allocator, class Allocator = std::
allocator<void*> >
  class ptr_list
  :
  public ptr_sequence_adapter< T, std::list<void*,Allocator>, CloneAllocator >
  {
  };
  struct B {
    typedef boost::ptr_list<B> C;
    C c;
