Sorry about that.  It's probably a clang bug.  I updated clang on those machines (needed to rebuild it to get clang-tidy, for which we'll set up a new dashboard soon) but I must have hit a bum svn revision, which happens sometimes when I rebuild clang from svn trunk.  I'm rebuilding clang now, if it's still broken, I'll restore the previous version, which I keep for this reason.

Cheers,
