What were the changes that you made to your program?

Two ideas I have might be to try gcc instead of clang, or to try a
different Boost version.  I don't think either of those is very likely
to work, though.  If you can paste some code that causes the error, I
can try to reproduce it; then, we can work towards a solution.

Thanks,

Ryan
