[Rcpp-devel] Segmentation Fault on Exit of RInside-using Programs

[Mario Bourgoin]

Dear Sir or Madam,

I first noticed this problem yesterday.  Every C++ program that
instantiates RInside has a segmentation violation upon exit.  (That's after
doing everything it was supposed to do the way it was expected to do it.)
What am I doing wrong?

A minimal example is

#include <RInside.h>
int main(int argc, char *argv[]) {
    RInside R(argc, argv);
    exit(0);
}

On

Ubuntu 10.04 LTS
R version 2.15.2 (2012-10-26) -- "Trick or Treat"
Rcpp version 0.10.1
RInside version 0.2.10

To clear up the problem this morning, I nuked all R system code (sudo
apt-get remove r-base) and packages from my machine (sudo rm -rf
/usr/local/lib/R and other places).  I freshly installed R (sudo apt-get
install r-base) and the RInside package (> install.packages( 'RInside' )).
I copied the rinside_sample0.cpp and its Makefile into a fresh directory,
added ``CXXFLAGS:=$(filter-out -O3,$(CXXFLAGS))'' to the Makefile to
facilitate debugging, compiled

$ make rinside_sample0
g++ -I/usr/share/R/include -I/usr/local/lib/R/site-library/Rcpp/include
-I/usr/local/lib/R/site-library/RInside/include -pipe -g -Wall
rinside_sample0.cpp  -L/usr/lib64/R/lib -lR  -lblas -llapack
-L/usr/local/lib/R/site-library/Rcpp/lib -lRcpp
-Wl,-rpath,/usr/local/lib/R/site-library/Rcpp/lib
-L/usr/local/lib/R/site-library/RInside/lib -lRInside
-Wl,-rpath,/usr/local/lib/R/site-library/RInside/lib -o rinside_sample0

and ran the code to get

$ ./rinside_sample0
Segmentation fault

In gdb I get

$ gdb ./rinside_sample0

41    ../inst/include/Rcpp/iostream/Rostream.h: No such file or directory.

I have downloaded the RInside and Rcpp sources and will reinstall them,
hopefully without -O3 and with -g so I can get more informative results.

Sincerely,
Mario
