Running the enumerator from QextSerialPort

[Sherban]

Hello I'm trying to get QT to communicate with my arduino board on a serial communications port. My application worked in eclipse but not on QT I did some research and it looks that QextSerialPort project would do the job. I tried running their example enumerator

#include <QtCore/QCoreApplication>
#include "qextserialenumerator.h"
#include "stdio.h"
 
using namespace std;
 
int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
 
          QList<QextPortInfo> ports = QextSerialEnumerator::getPorts();
          printf("List of ports:\n");
          for (int i = 0; i < ports.size(); i++) {
                printf("port name: %s\n", ports.at(i).portName.toLocal8Bit().constData());
                printf("friendly name: %s\n", ports.at(i).friendName.toLocal8Bit().constData());
                printf("physical name: %s\n", ports.at(i).physName.toLocal8Bit().constData());
                printf("enumerator name: %s\n", ports.at(i).enumName.toLocal8Bit().constData());
                printf("===================================\n\n");
        }
        return a.exec();
}

#include <QtCore/QCoreApplication>
#include "qextserialenumerator.h"
#include "stdio.h"

using namespace std;

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

          QList<QextPortInfo> ports = QextSerialEnumerator::getPorts();
          printf("List of ports:\n");
          for (int i = 0; i < ports.size(); i++) {
                printf("port name: %s\n", ports.at(i).portName.toLocal8Bit().constData());
                printf("friendly name: %s\n", ports.at(i).friendName.toLocal8Bit().constData());
                printf("physical name: %s\n", ports.at(i).physName.toLocal8Bit().constData());
                printf("enumerator name: %s\n", ports.at(i).enumName.toLocal8Bit().constData());
                printf("===================================\n\n");
        }
        return a.exec();
}

What I end up getting is "../enumerator.exe exited with code -1073741515". When I try to debug it I get an error "During startup program exited with code 0xc000..."

after some commenting, it turns out "QextSerialEnumerator::getPorts()" is to blame, because if I comment it out I can debug that program.

Does anyone have idea why would a call to a function cause such behaviour ?
