Yes, looks like a problem. Maybe the checkout failed at some point for the 
tester, and Boost.Optional submodule was left in outdated state. I sometimes 
get timeouts from GitHub when I update Boost tree, I think in such cases the 
tree is left in some semi-updated state; I didn't check though. If the update 
scripts ignore such errors then that's what may have happened.
