Thanks!
We need to wait for 3.3.8 to also be available in RcppEigen because that is what rstan uses and we want to be in-sync. We could also just upgrade as:
I asked the Rcppeigen devs on the timeline and if any of us can help: https://github.com/RcppCore/RcppEigen/issues/91
There is a build failure with Eigen 3.3.9 (and possibly 3.3.8). I get

This is with Stan Headers set to develop Stan Math or Stan Math 3.4.0? Or current CRAN StanHeaders?
Current everything on CRAN except drat RcppEigen 3.3.9. I should have probably included more of the error message:

It seems that an emergency StanHeaders will have to uploaded to CRAN that branches on EIGEN_MINOR_VERSION
in order to preserve compatibility with all the existing CRAN packages and pave the way for RcppEigen to upgrade to 3.3.9. Do we at least understand what we have to do with the 8 vs. 9 template arguments to the NumTraits thing?
I know there was an update not too long ago but there seems to be plenty of bug fixes since. See the changelog.
