| Can you chase down where the segfault happens?
In different places. Sometimes in R_gc_internal, sometimes in malloc. I've prepared an independent example so that you can try to reproduce it (below). Behavior is different but related to what I initially observed.
Steps to reproduce:
1. Create a skeleton package rcppdftest via Rcpp.package.skeleton.
2. Copy the following to rcpp_hello_world.cpp:
#include "rcpp_hello_world.h"
struct static_init {
std::vector<std::string> src, type;
static_init() {
src.push_back("AAAAAA");
src.push_back("BBBBBB");
src.push_back("CCCCCC");
src.push_back("DDDDDD");
src.push_back("EEEEEE");
src.push_back("FFFFFF");
type.push_back("A");
type.push_back("B");
type.push_back("C");
type.push_back("AA");
type.push_back("BB");
type.push_back("CC");
}
};
static static_init _static_init;
SEXP rcpp_hello_world(SEXP rlen) {
using namespace Rcpp ;
try {
int len = Rf_isNumeric(rlen) ? as<int>(rlen) : ::atoi(as<std::string>(rlen).c_str());
std::vector<double> vt, vpx, vsz;
std::vector<std::string> vsrc, vtype;
for (int i = 0; i < len; ++i) {
vt.push_back(1.0 * std::rand() / RAND_MAX);
vpx.push_back(10.0 * std::rand() / RAND_MAX);
vsz.push_back(100.0 * std::rand() / RAND_MAX);
size_t j = std::min(_static_init.src.size() * std::rand() / RAND_MAX, _static_init.src.size()-1);
vsrc.push_back(_static_init.src[j]);
size_t k = std::min(_static_init.type.size() * std::rand() / RAND_MAX, _static_init.type.size()-1);
vtype.push_back(_static_init.type[k]);
}
Rcpp::DataFrame df = Rcpp::DataFrame::create(
Rcpp::Named("t", vt),
Rcpp::Named("type", vtype),
Rcpp::Named("src", vsrc),
Rcpp::Named("px", vpx),
Rcpp::Named("sz", vsz)
);
return Rcpp::wrap(df);
} catch(const std::exception &error) {
forward_exception_to_r( error );
} catch(...) {
::Rf_error( "c++ exception (unknown reason)" );
}
return Rcpp::wrap(Rcpp::DataFrame());
}
3. Make corresponding changes to .h and .R.
4. Build and install.
5. Open R session and do the following:
> library(rcppdftest)
Loading required package: Rcpp
> tmp=rcpp_hello_world(50000)
> v=tmp$sz
> tmp=rcpp_hello_world(50000)
> v=c(v,tmp$sz)
> tmp=rcpp_hello_world(50000) <-- and here R session hangs forever.
When attaching with gdb, the call stack looks like the following:

Hope this helps.

| As expected, switching to std::vector did not make any difference. The following leads to the same behavior:

| std::vector<double> vt, vpx, vsz;
| std::vector<std::string> vsrc, vtype;
|
| // ... initializing the above vectors here

| Rcpp::DataFrame df = Rcpp::DataFrame::create(

|
| return Rcpp::wrap(df);
|
| It crashes inside the "create" function when the vector size is about 100K. Note that I was able to create a similar data frame of even much bigger size in R directly (without Rcpp).
Can you chase down where the segfault happens?
| What contribution are you talking about? Please clarify.
Feel free to quote. I wrote
| There is simply no wrap() support for Boost. Care to contribute it?
and the Rcpp-extending vignette details how to extend as<>() and wrap() to different classes. I was of course speaking half jokingly as Boost is no small feat---but it would be nice to have Boost support! Someone's gotta do it though.
Fixing the bug may be more important. If you can help there, we would appreciate it.
Cheers, Dirk

| |
| |
| |
| | DataFrame df = Rcpp::DataFrame::create(

| |
| | );
| |
| |
| |

|
| I'd start by disentangling this. Start with one object. Assign it from a Boost type a standard STL type _for which we have wrap() support_ and stick that in a data.frame.
|
