QJsonObject repetitive write - possible bug

  • I have a large QJsonObject (size of ~40 Mb when saved to json file).

    I call this procedure from the GUI:

      QJsonObject jRC = obj->js["a1"].toObject();
      obj->js["a1"] = jRC;

    Note that "a1" holds the most of the content of that object.
    After about ten successful calls I get an error:
    QJson: Document too large to store in data structure

    This is just a demonstrator, I have the same problem in my code.
    Any way around this issue?

    I am using Qt 5.8.0 (Windows 7, MSVC2013 )
