That doesn't sound accurate to me. TYPE_FACTORY returns a _copy_ of the static
shared_ptr. Also, the thread stacks you posted don't show any call to
TYPE_FACTORY, so it seems unlikely that it plays a part here.
After googling a bit, it seems TSAN sometimes produces false positives with
gcc. That may be one of those. Perhaps you can try with clang?

> TYPE_FACTORY() macro that produces type shortcuts (boolean(), int32(), utf8()
> and so on) uses static shared_ptr inside. There are race conditions possible
> against shared_ptr's reference counter.
