Assertion `ReferencesToBeSet.empty() && "Some objects had a reference that was not created"' failed.

Using arbitrary GCC 4.8.0+, I can see:

$ cat ipa-icf.ii
template < typename _Tp>
class Trans_NS___cxx11_list
    {
  

typedef _Tp iterator;

typedef _Tp _Node;
  _Node _M_create_node();

public:
  iterator end() ;
  void push_back(_Tp ) { _M_insert(end()); }
  template < typename... _Args > void _M_insert(_Args ... ) {
    _M_create_node();
  }
};
class sem_item_optimizer {
Trans_NS___cxx11_list< int * > worklist;
  void worklist_push();
};
int *worklist_push_cls;
void sem_item_optimizer::worklist_push() {
  worklist.push_back(worklist_push_cls);
}

$ g++ /tmp/ipa-icf.ii -g -c -O2
$ ./bin/diva ipa-icf.o
