--- Comment #7 from Jack Howarth <howarth.at.gcc at gmail dot com> ---
Also, note that upstream has in compiler-rt/cmake/config-ix.cmake...

    if(SANITIZER_MIN_OSX_VERSION VERSION_LESS "10.7")
      message(FATAL_ERROR "Too old OS X version: ${SANITIZER_MIN_OSX_VERSION}")
    endif()

so they haven't allowed building on 10.6 since
