[ Random thought: I might make people a bit more sympathetic for your cause
and questions if you pointed out that a) you are selling a db solution, b)
that these days Vertica is part of HP and c) the code for the R integration
is apparently on GitHub: https://github.com/vertica/DistributedR (or at least
that is where I think it may be). Why you guys never announced that here
is a bit of a mystery to me. ]

Well, consider that
a) I (and others) develop on Ubuntu 14.04. Things work on Ubuntu 14.04
b) CRAN tests all packages on several backends, including Ubuntu, Debian,
FC, OS X and Windows and would tell me (as maintainer) in no uncertain
terms if it didn't work.
c) So if it fails to work for you, maybe assume a local issue first?

|
| #include <RInside.h>
|

| {
|
| std::getchar();
That line makes little sense. I omitted it.
|
| 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);
| }
Works fine here:
edd at max:~/git/rinside/inst/examples/standard$ cat rinside_vertica.cpp
#include <RInside.h>
int main(int argc, char *argv[])
{
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);
}

Hello, world!

I maybe running github versions of Rcpp and/or RInside, but the only thing
that may matter is that you probably should
a) install Rcpp from source
b) install RInside from source
and then build these examples.
A reproducible issue may help. This was not reproducible. Or rather, this
may not even have been a bug.
Regards, Dirk
