The issue is that when calling wrap it creates an unprotected SEXP, and Rcpp is not responsible for these. If the programmer passes an unprotected SEXP to ::create, it is his responsability to protect it.
Just to clarify -- in the case of a naive user who's not protecting objects: a single wrap as the last call in a function is one case that will *always* work as expected, correct? And when using more than one wrap, later ones can *potentially* but not necessarily clobber earlier ones, yes? thanks, -christian
