Looks like it's an issue with the use of std::future on this particular architecture.
This is brand new code from @winsvega for adding the dots to keep TravisCI alive, which is obviously constraining portability. We should probably do something simpler with std::thread instead.
This particular error log is for the armel cross-build (armv5) but it looks like there are probably more.
