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

[Henrik Singmann]

Dear list,

I have the following weird problem and would be really glad for any input:

The windows binary from CRAN for my package MPTinR, which uses RcppEigen, leads to an "Assertion failed" error which crashes R with a simple example given below (which unfortunately is not part of the examples and henceforth not tested by CRAN).

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.

###### code starts #######
require(MPTinR)
data(d.broeder)
m.2htm <- system.file("extdata", "5points.2htm.model", package = "MPTinR")
get.mpt.fia(d.broeder, m.2htm)
###### code ends #######

The complete error message is:

###### error message starts #######
Assertion failed!

Program: C:\Program Files\RStudio\bin\x64\rsession.exe
File: d:/RCompile/CRANpkg/lib/3.1/RcppEigen/include/Eigen/src/Core/ProductBase.h, Line 95

Expression: a_lhs.cols() == a_rhs.rows() && "invalid matrix product" && "if you wanted a coeff-wise or a dot product use the respective explicit functions"

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
###### error message ends #######

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.

Best,
Henrik
