[Rcpp-devel] RcppEigen: Windows binary from CRAN crashes R, but not when installing from source.

| Interestingly enough, the problem disappears when installing the package on Windows from source or when using Linux (Ubuntu). But it also appears when using a binary version of MPTinR from winbuilder (temporarily available here: http://win-builder.r-project.org/h18PJ7B55VAq), R-devel and corresponding binary from CRAN, and I could replicate the error on a range of different Windows machines. The error also always disappears when installing from source. I am also extremely confident that this problem didn't exist in the past, I and others have used this functionality regularly with the CRAN windows binary.

| When adding such an example to the code and resubmitting it to winbuilder it now also crashes, see http://win-builder.r-project.org/0ei38q0t48h2/00check.log
| But again, when installing the same package on my machine from source it works.

It would help us if you could create a minimally reproducible example exhibit
this behaviour.

About 24 CRAN packages use RcppEigen.  The error could be yours, or ours. But
given the information provided so far it is hard to say more.

You could also try R along with valgrind on Linux to see if that tickles it.
