[geos-devel] Simple example (20 lines of code) crashes, but why ?

[Yücel Ahi]

Hi,

my very simple sample code (below) crashes when i call isValid(). Can
anybody reproduce the problem or know what the problem might be ?

Thanks in advance.

#include "geos/geom/Coordinate.h"
#include "geos/geom/CoordinateArraySequence.h"
#include "geos/geom/LineString.h"
#include "geos/geom/LinearRing.h"
#include "geos/geom/GeometryFactory.h"

using namespace geos::geom;

int main(int argc, char *argv[])
{
        CoordinateArraySequence* coords = new CoordinateArraySequence();

        //Simple rectangle
        coords->add(Coordinate(-1, 1));
        coords->add(Coordinate( 1, 1));
        coords->add(Coordinate( 1,-1));
        coords->add(Coordinate(-1,-1));
        coords->add(Coordinate(-1, 1));

        GeometryFactory factory;
        LinearRing* linearRing = factory.createLinearRing(coords);
        bool yes = linearRing->isValid(); // <---- Crashes here !!!

        return 0;
}
