POSIX doesn't say anything about C++, and C++ doesn't say anything about threads - we are already outside the scopes of these standards. A reasonable extension of C++ to multithreading should give static locals the semantics analogous to pthread_once. This allows to write code which uses lazy initialization, is MT-safe, yet doesn't use a threading library explicitly - is portable to C++ without threads. Note that this doesn't break any correct program which doesn't make use of this. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20099
