From f993b8754080ac7572b692870e926d8b493db16c Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Wed, 10 Jan 2018 13:18:04 +0100 Subject: nptl: Open libgcc.so with RTLD_NOW during pthread_cancel [BZ #22636] Disabling lazy binding reduces stack usage during unwinding. Note that RTLD_NOW only makes a difference if libgcc.so has not already been loaded, so this is only a partial fix.
