[Rcpp-devel] Have I noticed memory management bug in RcppArmadillo or is this the intended behaviour?

Memory returned to R is freed when R decides to free it.

To make your "tests" comparable, all (incl Rcpp, RcppArmadillo, R API and R
function) have to create and return the same object --- test with identical()
or at least all.equal().  Easiest to do by returning a single NULL (via
R_NilValue) and nothing else.

You returned larger objects from RcppArmadillo / fastLm() so maybe those hang
around longer.
