I would've expected significantly fewer test failures for clang -std=c++0x -stdlib=libc++:

However it has been a couple of months since I actually ran the full test suite (been busy elsewhere).  Did you get libc++abi.dylib from here:

http://home.roadrunner.com/~hinnant/libcppabi.zip

?

http://libcxx.llvm.org/ says:

This library implements things like exception handling.  Lack of this library might explain your failure rate.

If that isn't it, email me privately your entire results and I'll take a look.
