There is a race condition the threads in pool might access sync_point after
sync_point is destroyed.
If you swap the declarations the the threads in the pool are joined bevore
sync_point is destroyed

I didn't see this when it got reported. It is definitely a race condition.
UBsan is telling you about a real bug in the program.
