Hi, I'm working on building GCC 7.3 on Centos6.8. I'm running in the same issue as described in GCC bug ticket 79427: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79427 FAIL: g++.dg/tls/thread_local-order2.C -std=c++11 execution test FAIL: g++.dg/tls/thread_local-order2.C -std=c++14 execution test The executable runs into abort() caused by a wrong destruction order tracked by counter variables due to a possible malfunction of thread_local My libc is glibc-2.12-1.192.el6.x86_64 binutils are binutils-2.20.51.0.2-5.44.el6.x86_64 My configure flags are: --disable-libstdcxx-pch \ --disable-multilib \ --enable-shared \ --enable-static \ --enable-__cxa_atexit \ --enable-tls \ --enable-clocale=gnu \ --enable-threads=posix \ --enable-languages=c++ \ --enable-ld=yes \ --enable-gold=yes \ CC=/usr/bin/gcc \ CXX=/usr/bin/g++ \ --with-build-config=bootstrap-O3 I appreciate any hint to overcome this issue. Thanks, Jan
