From b2369ca3ff0cd75a30eb707537f83520c6fb1916 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Fri, 27 Oct 2006 18:43:38 +0000 Subject: [BZ #3429] 2006-10-27 Ulrich Drepper [BZ #3429] * elf/dl-open.c (dl_open_worker): Keep holding dl_load_lock until we are sure we do not need it anymore for _dl_close. ALso move the asserts inside the lock region.
