Over stack

[sangseu]

I'm using your library with ESP8266-07. Code:
aJsonObject *root, *data;
root = aJson.createObject();
aJson.addItemToObject(root, "data", data = aJson.createObject());
aJson.addNumberToObject(data, "hum", f_soi);
aJson.addNumberToObject(data, "tem", f_tem);
clientPS.publish(mqtt_topic_pub_soi, aJson.print(root));
//take care this
aJson.deleteItem(root);

It take ESP reset because over stack.
