From ea00486e438775bc37ee8e47e66225618cf717bc Mon Sep 17 00:00:00 2001 From: Geoffrey Keating Date: Mon, 14 Jul 2003 23:04:30 +0000 Subject: [PATCH] unwind-dw2-fde-darwin.c (live_image_destructor): Get seen_objects and unseen_objects from the global data before calling... * 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.
