It's been a while since I have seen such a segfault, but I have encountered
plenty in both the earlier days of Rcpp, or when working with for example the
geospatial satck. And it almost always traced back to different (binary,
i.e. 'native' code containing) packages requiring a rebuild. While I haven't
seen it lately, my suggestion would still be to see if it persists if you
rebuild everything touched by that package / if it happens for subsets of
these packages. Subsetting to the other native packages may suffice. From a
quick check (see below) that is still 16 packages.
