Yes (so no attempt at instrumentation has been made) other than doing the build out of tree (in tree gave the same result), the example I got (clang test.cpp -stdlib=libc++) is from there.

This may have changed recently. Did you follow "Build on Linux using CMake and libsupc++" section on libc++ site?
