Segfault in Boost

I'm getting a segfault in Boost when I go to use mutexes. I built the Boost unit test for threads with the following: bjam "-sTOOLS=gcc" "-sBUILD debug <runtime-link>static <threading>multi" In Boost 1.32 there are errors with text_mutex_lib: root@unstable:~/scratch/boost_1_32_0/bin/boost/libs/thread/test/test_mutex_lib.test/gcc/debug/runtime-link-static/threading-multi> ./test_mutex_lib Running 6 test cases...

It seems the unit test Boost has are making calls to libthreaddb.so (NPTL). Anyone have any ideas? I've reproduced this on 2 machines (opterons 246), 2 distros now. What really boggles me is that the one xtime test works on 1.33 but the mutex test doesn't. Simple mutex calls work fine however. Are these specific problems with the test or something deeper? I've seen no discussion on the mailing list.
