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?
I think you are right.
And when using more than one
wrap, later ones can *potentially* but not necessarily clobber earlier
ones, yes?
This is what makes it difficult to detect. You never know when garbage
is being collected.
thanks,
