Exception while closing gateway

[AdamMachera]

I'm creating gateway from c# using those function

    [DllImport("gateway.dll", CharSet=CharSet.Ansi, EntryPoint = "Gateway_CreateFromJson", CallingConvention = CallingConvention.Cdecl)]
    public static extern IntPtr GatewayCreateFromJson([MarshalAs(UnmanagedType.LPStr)] string filePath);
    [DllImport("gateway.dll", EntryPoint = "Gateway_Destroy", CallingConvention = CallingConvention.Cdecl)]
    public static extern IntPtr GatewayDestroy(IntPtr gateway);

Gateway is using nodejs and c# modules.
From time to time if I try to close gatewat I'm getting exception from node.cc
Bolded code throws exception:

Unhandled exception at 0x00007FF8F5016DF0 in IoTClient.exe: 0xC0000005: Access violation executing location 0x00007FF8F5016DF0.

if (instance_data->use_debug_agent())
  EnableDebug(env);

{
  SealHandleScope seal(isolate);
  bool more;
  node::node_loop_func loop_func = instance_data->loop_func();
  do {
    if(loop_func != NULL) {
      loop_func(isolate);
    }
    **v8_platform.PumpMessageLoop(isolate);**
    more = uv_run(env->event_loop(), UV_RUN_ONCE);

    if (more == false) {
      v8_platform.PumpMessageLoop(isolate);
      EmitBeforeExit(env);

      // Emit `beforeExit` if the loop became alive either after emitting
      // event, or after running some callbacks.
      more = uv_loop_alive(env->event_loop());
      if (uv_run(env->event_loop(), UV_RUN_NOWAIT) != 0)
        more = true;
    }
  } while (more == true);
}
