signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x8 , when user polygon dynamic add points quickly #545

Closed baneyue closed 2 months ago

baneyue commented 2 months ago

When using polygons and dynamically adding points quickly, the MTK CPU Android 12 tablet shows NE

The usage of layers is as follows and add points frequency of 10ms once ` // init layers projection = new EPSG3857(); dynamicTrackSource = new LocalVectorDataSource(projection, LocalSpatialIndexType.LOCAL_SPATIAL_INDEX_TYPE_KDTREE); mSprayLayer = new VectorLayer(dynamicTrackSource); mapView.getLayers().add(mSprayLayer); mSprayLayer.setVisibleZoomRange(new MapRange(10, 24)); dynamicTrackSource.setGeometrySimplifier(null);

   // add points
   val mapPosVector = MapPosVector()
   if (polygon == null) {
            if (polygonPointList.isEmpty()) {
                mapPosVector.add(leftPoint)
                mapPosVector.add(rightPoint)
                polygonPointList.add(leftPoint)
                polygonPointList.add(rightPoint)
            } else {
                val half = polygonPointList.size / 2
                polygonPointList.add(half, leftPoint)
                polygonPointList.add(half + 1, rightPoint)
                polygonPointList.forEach { mapPosVector.add(it) }
            }
            val polygon = Polygon(mapPosVector, polygonStyle)
            dynamicTrackSource?.add(polygon)
            this.polygon = polygon
        } else {
            val half = polygonPointList.size / 2
            polygonPointList.add(half, leftPoint)
            polygonPointList.add(half + 1, rightPoint)
            polygonPointList.forEach { mapPosVector.add(it) }
            polygon?.poses = mapPosVector // **the crash line**
       }

` Is it Command reordering exception in Android native ? The usual solution to this problem is to use memory barriers or atomic operations to prevent instruction rearrangement. In C or C++code, you can use atomic variables from the atomic library
