The OP can fix the problem by eliminating that assumption. Either of
the statements below will work:

  testselect.push_back(&(*test_itr));
  testselect.push_back(test_itr.operator->());

Also note that if you ever resize/reserve/push_back or modify
the 'testlist' vector, all of the pointers in 'testselect' become
invalid. Generally, it is not a good idea to have pointers to the
inside elements of a container which can move its elements around.
