For what it's worth, running "ninja check-all" on my ubuntu machine is
failing several of these tests. Do you know anything about this?
Failing Tests (4):
ThreadSanitizer :: race_on_mutex.c
ThreadSanitizer :: simple_stack.c
ThreadSanitizer :: simple_stack2.cc
ThreadSanitizer :: write_in_reader_lock.cc
for example:
FAIL: ThreadSanitizer :: simple_stack.c (12713 of 12789)
******************** TEST 'ThreadSanitizer :: simple_stack.c' FAILED

> [TSan] port all output tests to lit and move them to lit_tests directory. This makes 'make check-tsan' command test both unit and output TSan tests. Old custom makefiles for running TSan tests are still functional as well.
