Hi all, I just double checked the compilation flag on win-builder. It turns out that it uses -O3 as François pointed out, and also the -DNDEBUG flag is NOT defined, unlike the default configuration shipped with R for windows.
Under these conditions, the issue can actually be reproduced. I'm not sure whether this is a bug of MinGW or of Eigen, but at least we can start from here to investigate. (I would suggest future discussions moving to https://github.com/RcppCore/RcppEigen/issues/34) Best, Yixuan -- Yixuan Qiu <yixuan....@cos.name> Department of Statistics, Purdue University _______________________________________________ Rcpp-devel mailing list Rcpp-devel@lists.r-forge.r-project.org https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/rcpp-devel
