Marking this as critical because it is stopping DXR from updating.

My belief is that it's a libstdc++ headers problem, and that building with gcc 4.7 libstdc++ ought to work. It will require rebuilding clang with build/unix/build-clang/build-clang.py, in an environment where our gcc 4.7 (bug 850689) is installed, and with a modification to --with-gcc-toolchain in build-clang.py.
