This test is failing with following report:

==4793==WARNING: MemorySanitizer: use-of-uninitialized-value
    #0 0xfff51d13e0 in Thread1 llvm/projects/compiler-rt/test/msan/dtls_test.c:22:7
    #1 0xfff5149114 in MsanThreadStartFunc(void*) llvm/projects/compiler-rt/lib/msan/msan_interceptors.cc:1238
    #2 0xfff50a4cf4 in start_thread /build/glibc-g99ldr/glibc-2.19/nptl/pthread_create.c:311

Is it a known issue? I am unable to visit issue #44 because of transition of google code.
