Damn. Confirmed. Running 'make clean && make && make runAll' in the
examples/standard directory of RInside shows that I get the segfaults too.  

That really should not have slipped through -- my bad.  There will be an Rcpp
0.9.13 shortly.  

In the meantime, you can probably downgrade to version 0.9.10-1 from Debian
testing, or build from SVN.
