I just got R installed on an Ubuntu VM, and ran "R CMD check 
huxtable_4.0.1.tar.gz" both with and without "--as-cran", without seeing 
the error you quoted.  (I did see other problems, related to not having 
things like pandoc installed; nothing that looked like a problem with 
the package rather than a problem with my R installation.)

That looks like a bug, but without having a system that can reproduce 
it, it's hard to narrow down where:

  - In R's checks?  Seems unlikely, given it is so system specific.
  - In CRAN's scripts?  Really unlikely, since all the tests are in R.
  - In huxtable or some package used by huxtable?  Seems possible: 
maybe memory got corrupted.  Perhaps running under some memory checker 
would be more informative.

Perhaps the CRAN team could be helpful here.

Given that the error is unrelated to the solution, it really looks like 
memory corruption somewhere or other.
