如何在OSX上使用clang线程消毒剂？

Question

我试图--thread-sanitizer在OSX上使用clang的选项:

$ clang++ -fthread-sanitizer -fpic tsan1.cc
Apple LLVM version 4.2 (clang-425.0.24) (based on LLVM 3.2svn)
Target: x86_64-apple-darwin12.3.0
Thread model: posix
[...]
clang -cc1 version 4.2 based upon LLVM 3.2svn default target x86_64-apple-darwin12.3.0
[...]
Undefined symbols for architecture x86_64:
  "___tsan_func_entry", referenced from:
      threadfunc(void*) in tsan1-6f7gbr.o
[...]
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

看起来像一个链接错误.我应该链接一些额外的库吗？

Darwin 上的 C++ 尚不支持 ThreadSanitizer。这种情况至少半年内不太可能改变。
