Remove the RayCastVehicle Node

In Sample 46 RayCastVehicle Demo,
1 Removing the Vehicle Node and all it’s child Wheel nodes
2 Recreating the Vehicle, got the following crash:

Which version hash do you use? Also could you please report to github?

Also could you please attach text log dump of backtrace?

// Code In Extended Application to remove the vehicle
//Node* vehicleNode;

Vehicle* vehicle = vehicleNode->GetComponent<Vehicle>();
bool sameNode = vehicle->GetNode() == vehicleNode;
vehicle->Destroy();
scene_->RemoveChild(vehicleNode);

// Here I want to remove the emitter nodes and all the wheel nodes.

void Vehicle::Destroy()
{
    for (int i=0; i<particleEmitterNodeList_.Size(); ++i)                                                                           
        GetScene()->RemoveChild(particleEmitterNodeList_[i]);
    particleEmitterNodeList_.Clear();
    RaycastVehicle* vehicle = node_->GetComponent<RaycastVehicle>();
    for (int i=0; i<vehicle->GetNumWheels(); ++i)
        GetScene()->RemoveChild(vehicle->GetWheelNode(i));

    //delete vehicle;
}

I don’t know if it’s the correct way to remove the vehicle. The crash happens after recreating the vehicle.

Just deleting node, as long as RemoveComponent should work.
If they don’t you better submit a bug with full backtrace and complete code sample, I will resolve it.
Please do it on github.

It works on Linux platform, but crashs on Android.
