The intention is to use pthread_setattr_default_np followed by a call to std::thread contructor, because the latter doesn't allow specifying the thread attribute. So, instead of: pthread_attr_t attr; <initialize attr> pthread_create(..., &attr, ...) Use: pthread_attr_t attr; <initialize attr> pthread_setattr_default_np(&attr) std::thread t(...); But this race condition prevents such usage of pthread_setattr_default_np. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1844022 Title: pthread_setattr_default_np race condition with pthread_create.
