Not really.  A minimal reproducible example would help.

The corpus of now 180 packages at CRAN work across OS X, Windows and Linux;
as do 19 BioC packages in the next release plus an unknowable number of
private packages.

But there can always be fresh bugs in unseen code. But to fix something, it
helps tremendously to be able to reproduce it.

Can you assist with a small example?

As you never got a reproducible example, let me jump in to this old
thread as the error discussed, viz.
   class Rcpp::InternalFunction_Impl<Rcpp::PreserveStorage>' has no
member named 'update'
comes up with both the version of Rcpp on CRAN as well as the version
on github when running
this reproducible example:

code <- '
#include <Rcpp.h>
using namespace Rcpp ;

void callback(){
    Rprintf( "hello from calback\n" ) ;
}

// [[Rcpp::export]]
InternalFunction get_callback(){
    return InternalFunction(&callback) ;
}
'
library(Rcpp)
sourceCpp(code = code, verbose = TRUE)

This example is from Romain who posted it on SO here some time back
except I added a & before callback in the last line.

I am on Windows 8.1 and am using  "R version 3.1.0 Patched (2014-05-08 r65552)"

(Note that the version of Rcpp on github fails when installing during
building the vignette so I built it without vignettes; however, the
problem occurs on the CRAN version too as mentioned.)

The vignettes build fine for me. Can you provide more information
(perhaps as a GitHub issue)?

I'll take a look at InternalFunction. I think there was something
similar reported earlier.

Cheers,
Kevin
