Worth stressing that this happens under link-time optimziation (lto) which I am not yet that familiar with. From _really briefly_ glancing at your package I see that you include RcppArmadillo.h in some files (good !) but also include armadillo directly. It's just a hunch and guess at this point but that may lead to different 'settings' and #define values. Maybe try using only RcppArmadillo.h ?
