Unittest stops on an assert pthread_attr_setdetachstate(&attr, detached)

OS: Darwin, OS X 10.6.8 64-bit in 32-bit mode

I'm starting the demo test with the following command:
sudo ./valgrind --tool=tsan 
/Users/Shared/threadsanitizer/drt/unittest/bin/demo_tests-darwin-x86-O1

and getting the following output:

Is there some workaround for this problem?

To work around this you can find the corresponding line in the source code 
(line 341 in thread_wrappers_pthread.h) and replace the CHECK with some code 
that prints the result of pthread_attr_setdetachstate(). Most certainly you can 
just comment this line out, but printing the error code will give us an idea 
about what's going on.

The pthread_attr_setdetachstate function returns an error code 22 on my system 
(EINVAL, Invalid argument).
I commented this line and I got an output for the demo unit test after that. 
Thank you.
