The thread has been handled in Rcpp-devel. Rob posted there 7 minutes

FWIW, I think the problem is fixed on the Rcpp 0.7.11 version (on cran
incoming)

Rob,
Please look again at Romain's reply to you on 19th March. He informed you
then that Rcpp has its own dedicated mailing list and he gave you the link.

Hi,
I'm a bit puzzled. I uses exactly the same code in RcppExamples
package to try adding RcppFrame object to RcppResultSet. When running
it gives me segmentation fault problem. I'm using gcc 4.1.2 on redhat
64bit. I'm not sure if this is the cause of the problem. Any advice
would be greatly appreciated. Thank you.
Rob.
int numCol=4;
std::vector<std::string> colNames(numCol);
colNames[0] = "alpha"; // column of strings
colNames[1] = "beta"; // column of reals
colNames[2] = "gamma"; // factor column
colNames[3] = "delta"; // column of Dates
RcppFrame frame(colNames);
// Third column will be a factor. In the current implementation the
// level names are copied to every factor value (and factors
// in the same column must have the same level names). The level names
// for a particular column will be factored out (pardon the pun) in
// a future release.
int numLevels = 2;
std::string *levelNames = new std::string[2];
levelNames[0] = std::string("pass"); // level 1
levelNames[1] = std::string("fail"); // level 2
// First row (this one determines column types).
std::vector<ColDatum> row1(numCol);
row1[0].setStringValue("a");
row1[1].setDoubleValue(3.14);
row1[2].setFactorValue(levelNames, numLevels, 1);
row1[3].setDateValue(RcppDate(7,4,2006));
frame.addRow(row1);
// Second row.
std::vector<ColDatum> row2(numCol);
row2[0].setStringValue("b");
row2[1].setDoubleValue(6.28);
row2[2].setFactorValue(levelNames, numLevels, 1);
row2[3].setDateValue(RcppDate(12,25,2006));
frame.addRow(row2);
RcppResultSet rs;
rs.add("PreDF", frame);
