A good week after the update to Eigen 3.2.8 in our RcppEigen package 0.3.2.8.0, we have another (local) update with RcppEigen 0.3.2.8.1 which should fix another UBSAN issue. This new version in now on CRAN and in Debian. Big thanks once again to Yixuan Qiu for liasing with Eigen upstream, reporting the bug and preparing a PR with the fix.
The NEWS file entry follows.
Changes in RcppEigen version 0.3.2.8.1 (2016-02-29)
Applied another upstream UBSAN fix (PR #30 by Yixuan)
Courtesy of CRANberries, there is also a diffstat report for the most recent release.
