SIGSEGV at _dl_runtime_resolve_xsavec in boost::detail::set_current_thread_data #409
Description
I started running into this SIGSEGV. Is it possible that some thread-local variable initialization could trigger this? Any ideas for how to troubleshoot further? When I swap out boost::thread with std::thread, the SIGSEGV goes away. So far I haven't been able to reproduce the error with a simple example. I am using boost 1.84.0
Thread 5 "a.out" received signal SIGSEGV, Segmentation fault.
