Help find the error that sometimes causes the program to crash

[tarachom]

Sometimes when completely reloading the tree or even when first filling it, the program crashes with this error - Stack overflow.
Usually everything works perfectly but at some point this error crashes.

I'm not sure if I can help. I would need a minima sample from you to reproduce.

Can you provide a sample?

Example

Good afternoon! I have prepared an example that reproduces the structure of my program as much as possible. Previously, these were abstract classes, but for the 0.8.0-preview.1 version of GirCore.Gtk-4.0 I reworked them as Subclass. Maybe I made a mistake somewhere when reworking. First of all, I apologize for the bulky example, I tried to shorten it as much as possible. The error occurs both during the process of adding data and when a complete data reload occurs.

upd: This kind of error only occurs on Windows 11. Everything works fine on Ubuntu 22.04.1.
Ubuntu sometimes throws an error:

Unhandled exception. System.Exception: Could not toggle reference to strong. It got garbage collected.
   at GObject.Internal.ToggleRef.ToggleReference(Boolean isLastRef)
   at GObject.Internal.InstanceCache.ToggleNotify(IntPtr data, IntPtr object, Int32 isLastRef)

Sorry it will take some time. Perhaps I will have some time today to take a look.

[tarachom]

Good afternoon. The problem has been resolved at this time.

[badcel]

Do you mind sharing your solution?

I would like to make sure that your solution is not a workaround for a bug present in GirCore.

@tarachom can you provide some feedback?

Good afternoon! Sorry for not answering you in time because in fact I did not find a solution, just at some point after updating Windows and libraries (msys64) my accounting program started working normally sometimes crashes, but extremely rarely. Once I noticed a problem when I made changes to the base class and when filling the Gio.ListStore store the program froze. The next time I started everything started working normally. Maybe the problem occurs at the moment of restoring from the cache. But this is just a guess.
In this example (TreeExpanderTest2) that I prepared for you, you can still reproduce the error, but on a large amount of data and if you intensively update the list. I also want to say that on Ubuntu absolutely such a problem has never arisen, only in Windows.
