Looks like the code was unable to find an 8-byte aligned type. Could you check the results of: std::cout << boost::alignment_of<double> << '\n'; std::cout << boost::alignment_of<long double> << '\n'; I suspect they are both '4', but that leaves me even more confused as to why the alignment of std::pair<double, double> would be 8 (and how to get a POD type with alignment 8 for ourselves!).
