TheIDE pop out a message box as below when the programme is run step by step to CoreTutorial\Stream.cpp line 72.

Message box:
===

/// In `LoadThrowing` mode, `Stream` throws `LoadingError` exception when there is problem with
/// input `Stream`:

in.LoadThrowing();
try {
in.GetAll(999999); <--- line 72
}
catch(LoadingError) {
LOG("Loading error");
}

I comment out the above code, rebuild and run the programme.
It run further to CoreTutorial\Serialize.cpp line 42 and pop out the same message box.

Part of CoreTutorial\Serialize.cpp
===
/// When serialization fails to load the data (e.g. because of wrong structure or not
/// enough data in the stream), `Stream::LoadError` is invoked, which can trigger the
/// exception if the stream is `LoadThrowing`:

ss2.Seek(0);
ss2.LoadThrowing();
try {
ss2 % x2 % h2 % x2; <-- line 42
}
catch(LoadingError) {
LOG("Deserialization has failed");
}

Thank you for you attention.
