What is the proper way to detect if a node has been set up already/initialized?

I can't seem to find a good way of doing this, so I thought I'd ask here. In my little test app I want to see if a ma_reverb_node has already been configured and set up, but there isn't any kind of API to do that. So I tried to devise a way by checking if the node graph pointer was nullptr:

                if (!reverb.baseNode.pNodeGraph) {
                    auto config = ma_reverb_node_config_init(2, 44100);
                    config.roomSize = 100.0;
                    auto* node_graph = ma_engine_get_node_graph(&engine);
                    if (const auto res = ma_reverb_node_init(node_graph, &config, nullptr, &reverb); res != MA_SUCCESS) {
                        MessageBox(NULL, std::format("Error initializing MA reverb node: {}", res).c_str(), "Error", MB_OK | MB_ICONSTOP);
                        PostQuitMessage(0);
                    }
                    ma_node_attach_output_bus(&reverb, 0, ma_node_graph_get_endpoint(node_graph), 0);
                } else {
                    ma_reverb_node_uninit(&reverb, nullptr);
                }

However, The MSVC CRT really doesn't like this and complains about a debug heap free (perhaps a use-after-free or double free). Is there a more robust or "blessed"/recommended way of determining if a node has already been configured and set up?

You yourself initialize and uninitialize the node, so that must mean that your program already knows when it's initialized.

Ah okay, thanks :)
