[boost] [thread] Address sanitizer failures on marshall-mac

Hi, I'm observing Boost.Log and Boost.Atomic test failures on marshall-mac with AddressSanitizer enabled. http://www.boost.org/development/tests/develop/developer/output/marshall-mac... http://www.boost.org/development/tests/develop/developer/output/marshall-mac... The error messages don't contain function names but the backtraces have Boost.Thread on top. I can also see similar failures in Boost.Thread: http://www.boost.org/development/tests/develop/developer/output/marshall-mac... Is this a known problem in Boost.Thread? Can the backtraces be deciphered so that function names are shown?
