I'm here, but don't have any more info than Sean (actually less).  I don't have a linux box to test on.

The summary from my most recent test run on OS X (Lion) is:

****************************************************
Results for /test:
using Apple clang version 3.0 (tags/Apple/clang-211.10.1) (based on LLVM 3.0svn)
Target: x86_64-apple-darwin11.1.0
Thread model: posix
with -std=c++0x -stdlib=libc++  
----------------------------------------------------
sections without tests   : 1
sections with failures   : 19
sections without failures: 1044
                       +   ----
total number of sections : 1064
----------------------------------------------------
number of tests failed   : 75
number of tests passed   : 4249
                       +   ----
total number of tests    : 4324

And the bulk of those failures are as Sean describes (atomics, initializer lists).
