From 12f6282b6bf59d45934c78118ad5d26039fb533b Mon Sep 17 00:00:00 2001 From: Peter Seiderer Date: Fri, 16 Apr 2021 23:12:51 +0200 Subject: libpthread/nptl: create timer thread with sufficiant stack size (account for TLS) Create timer thread with sufficiant stack size (take into account allocated space for thread-local-storage), for this backport glibc commit 'Create internal threads with sufficient stack size' ([1], [2]) introducing __pthread_get_minstack() and use it in __start_helper_thread(). Fixes timer_create() in case of linking with library using large TLS area (e.g openblas, see [3]).
