Hi,
I have a custom application that uses Rcpp and Rinside to execute R code. All
was well until I was using R-3.0.0, Rcpp 0.10.2 and RInside 0.2.10 but now its
time to upgrade to the latest version and I can't get even the Rinside samples
to work in place of my application. My machine has Ubuntu14.04. The code
compiles fine but when I run it, I get a segfault during Rinside
initialization. I tried to troubleshoot by replacing my code by one of the
examples rinside_sample0. The example runs fine as is but if I add just a
single line "Rcpp::DataFrame p; " it segfaults again. Here is the complete
code. The same code works fine inside the Rinside examples directory.
#include <RInside.h>
int main(int argc, char *argv[])
{
std::getchar();
RInside R(argc, argv);
R["txt"] = "Hello, world!\n";
Rcpp::DataFrame pf; <-------- Runs fine if I comment out this line.
R.parseEvalQ("cat(txt)");
exit(0);
}
Here is the backtrace of the segfault
Program received signal SIGSEGV, Segmentation fault.

I also looked at the libraries that were being loaded at runtime and they are
exactly the same for both the rinside examples and my app. Pasted below for
completeness. I am out ofdebugging tricks to get this to work. Any ideas as to
what's wrong. what am I missing?
