	* unwind-dw2-fde-darwin.c (live_image_destructor): Get seen_objects
	and unseen_objects from the global data before calling
	__deregister_frame_info_bases.
	(examine_objects): Insert objects into the seen_objects list,
	not unseen_objects.
	(_Unwind_Find_FDE): Always unlock the global object lists, even if
	we couldn't allocate a data structure to put in it.
