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