[Rcpp-devel] Bug with table sugar and NumericVector in Rcpp 0.10.3

Hi guys,

When I attempt to 'sourceCpp' the following code, the R session
crashes:

#include <Rcpp.h>
using namespace Rcpp;

// [[Rcpp::export]]
IntegerVector counts(NumericVector x) {
? return table(x);
}

The same code worked in Rcpp 0.10.2.

A hint to the error comes if I try to compile a package with that
source code in a .cpp file: I get the error, when attempting to load
the package:

dlopen(/Library/Frameworks/R.framework/Versions/2.15/Resources/library/anRpackage/libs/x86_64/anRpackage.so,
6): Symbol not found:

__ZN4Rcpp8internal16coerce_to_stringILi14EEEPKcNS_6traits12storage_typeIXT_EE4typeE
 ? Referenced from:

/Library/Frameworks/R.framework/Versions/2.15/Resources/library/anRpackage/libs/x86_64/anRpackage.so
? Expected in: flat namespace
?in

/Library/Frameworks/R.framework/Versions/2.15/Resources/library/anRpackage/libs/x86_64/anRpackage.so

This is with R 2.15.3 on Mac OSX 10.8.3.

In addition, if I attempt to compile Rcpp from source (with gcc 4.8) 
I
get the following warnings:

install.packages("Rcpp", type="source",

although the package does install successfully. Not sure if it's
related or not.
