Actually, sorry, what I was talking about is a fix needed for the
multithreaded examples. It is coming "soon", there is just other (unrelated)
thing I need to take care of.

The segfault you see is an Rcpp issue we have fixed in SVN. It was simply
trying to delete something twice, hence the alarming-looking but ultimately
harmless, segfault notice. It will go away from you use the Rcpp from SVN, or
an older one.
