It turns out that the Octave problem has nothing to do with R or Rcpp.
This is a clash between Octave and MacOS, and there is also a problem
under Fedora Linux (or the Octave documentation is not up-to-date).

Process the attached file like so (under MacOS):
mkoctfile --link-stand-alone embedded.cc -o embedded

Note that most of the code in this file has been commented out,
leaving only the string_vector declaration at the top.

This is what happens when I run embedded:
/Users/dsamperi/c++bug $ ./embedded
embedded(64345) malloc: *** error for object 0x7fff7e114570: pointer being
freed was not allocated
*** set a breakpoint in malloc_error_break to debug
Abort trap: 6

If I uncomment the code and create embedded under Fedora Linux
I get an error saying gcd is not invoked properly. But this example
is copied directly from the documentation, so I guess it has not
been checked/updated for some time…
