GeometryComponentFilter::filter_ro is a virtual function. LinearComponentExtracter is the actual implementation for this case (see last step in trace). You would _always_ receive a SIGABRT if GeometryComponentFilter::filter_ro is entered rather than LinearComponentExtracter::filter_ro. Indeed GeometryComponentFilter::filter_ro and ::filter_rw could be made pure abstract methods. --strk; () Free GIS & Flash consultant/developer /\ http://strk.keybit.net/services.html _______________________________________________ geos-devel mailing list geos-devel@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/geos-devel
