-Tsan does not see synchronization in barrier_wait.
-ANNOTATE_HAPPENS_BEFORE/AFTER communicate the synchronization to tsan
-and prevent the race report.

-If the compiler does not support __has_feature macro, then you can build with
-CFLAGS="-fsanitize=thread -DTHREAD_SANITIZER" and then use
-#ifdef THREAD_SANITIZER to enabled annotations.
