Ptr member of ManagedStaticBase is now atomic. In ManagedStaticBase::RegisterManagedStatic we have such code: void *Tmp = Creator(); Ptr.store(Tmp, std::memory_order_release); DeleterFn = Deleter; // Add to list of managed statics. Next = StaticList; StaticList = this; StaticList is not atomic and not guarded by any fence. The same applies to the members

This code from raw_ostream.h is really racy: raw_ostream &operator<<(StringRef Str) { // Inline fast path, particularly for strings with a known length. size_t Size = Str.size(); // Make sure we can use the fast path. if (Size > (size_t)(OutBufEnd - OutBufCur)) return write(Str.data(), Size); if (Size) { memcpy(OutBufCur, Str.data(), Size);
