Seemingly starting with the most recent builds of R-devel, I�ve been getting
segfaults related to a piece of cpp code that indexes a zero-size
NumericVector. Essentially the same as this dummy example:
```
library(Rcpp)
sourceCpp(
code = '
#include
using namespace Rcpp;
// [[Rcpp::exp
I have a data package �pmartRdata� hosted in a drat repository here:
https://github.com/pmartR/drat following the instructions here:
https://cran.r-project.org/web/packages/drat/vignettes/DratStepByStep.html
The package installs fine via install.packages(�pmartRdata�, repos =
�https://pmartR.
