Hi,<br>
<br>
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.<br>
<br>
<pre>#include <RInside.h>
int main(int argc, char *argv[])
{
std::getchar();
RInside R(argc, argv);
R["txt"] = "Hello, world!\n";
Rcpp::DataFrame pf; <font color="#cc0000"><-------- Runs fine if I comment out this line.</font>
R.parseEvalQ("cat(txt)");
exit(0);
}
</pre>
Here is the backtrace of the segfault<br>
<br>

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?<br>
