I've been building and running the clang test releases and tests, as 
well as trunk on Ubuntu for a while with libc++ and libc++abi, it's been 
fine until the 3.5 RC1.

That is to say that the boost regression test suite that I also run and 
publish, seem to have a very similar pass rate as gcc.

I don't usually build libc++ and libc++abi in-tree with clang and llvm, 
but the clang release script was fine with 3.3, 3.4, 3.4.1, 3.4.2 and 
perhaps earlier.
