This is the reproduction I have, you need to keep moving the slider fast until it throws the above error or sefaults

import {
  Adw,
  Gtk,
  Gtk_,
  kw,
  NamedArgument,
  python,
} from "https://raw.githubusercontent.com/sigmaSd/deno-gtk-py/13f3da6c4890d62e09312747c905fa85263f5ca8/mod.ts";

class MainWindow extends Gtk.ApplicationWindow {
  #slider: Gtk_.Scale;
  constructor(kwArg: NamedArgument) {
    super(kwArg);
    this.set_default_size(600, 250);
    this.#slider = Gtk.Scale();
    this.#slider.set_range(0, 10);
    this.#slider.connect("value-changed", this.slider_changed);

    this.set_child(this.#slider);
  }

  slider_changed = python.callback(
    (_kwargs, slider: Gtk_.Scale): undefined => {
      slider.get_value(); // this line trigger the error/segfault
    },
  );
}

class App extends Adw.Application {
  #win: MainWindow | undefined;
  constructor(kwArg: NamedArgument) {
    super(kwArg);
    this.connect("activate", this.onActivate);
  }
  onActivate = python.callback((_kwarg, app: Gtk_.Application): undefined => {
    this.#win = new MainWindow(new NamedArgument("application", app));
    this.#win.present();
  });
}

const app = new App(kw`application_id=${"com.example.com"}`);
app.run(Deno.args);

    Here is an easier reproduction

    import {
  Adw,
  Gtk,
  Gtk_,
  kw,
  NamedArgument,
  python,
} from "https://raw.githubusercontent.com/sigmaSd/deno-gtk-py/0.1.4/mod.ts";

class MainWindow extends Gtk.ApplicationWindow {
  #blobs: [number, number][] = [];
  #dw: Gtk_.DrawingArea;
  constructor(kwArg: NamedArgument) {
    super(kwArg);
    this.set_default_size(600, 250);
    this.#dw = Gtk.DrawingArea();

    this.#dw.set_draw_func(this.draw);
    const evk = Gtk.GestureClick.new();
    evk.connect("pressed", this.dw_click);
    this.#dw.add_controller(evk);

    this.set_child(this.#dw);
  }

  draw = python.callback(
    (_kwargs, _area, c): undefined => {
      c.set_source_rgb(1, 0, 1);
      for (const [x, y] of this.#blobs) {
        c.arc(x, y, 10, 0, 2 * 3.1415926);
        c.fill();
      }
    },
  );
  dw_click = python.callback(
    (_kwargs, _gesture: Gtk_.GestureClick, _data, x, y) => {
      this.#blobs.push([x, y]);
      this.#dw.queue_draw(); // Force a redraw
    },
  );
}

class App extends Adw.Application {
  #win: MainWindow | undefined;
  constructor(kwArg: NamedArgument) {
    super(kwArg);
    this.connect("activate", this.onActivate);
  }
  onActivate = python.callback((_kwarg, app: Gtk_.Application): undefined => {
    this.#win = new MainWindow(new NamedArgument("application", app));
    this.#win.present();
  });
}

const app = new App(kw`application_id=${"com.example.com"}`);
app.run(Deno.args);

    click on the board multipe times fast enough and it will segfault

    seems like this vector_call thing is an optimization that is not correctly handled ?

    To catch the segfault , you need to run gdb like this G_DEBUG=fatal-criticals gdb --args deno run -A --unstable code.ts

    I found the weirdest fix , logging with Deno.stdout.write, somehow fixes the problem

    diff --git a/src/python.ts b/src/python.ts
index 66cf3bd..3bed6d8 100644
--- a/src/python.ts
+++ b/src/python.ts
@@ -470,6 +470,7 @@ export class PyObject {
             BigInt(Deno.UnsafePointer.value(Deno.UnsafePointer.of(nameBuf)!)),
             LE,

+          Deno.stdout.write(struct);
           const fn = py.PyCFunction_NewEx(
             struct,
             PyObject.from(null).handle,

    Also I noticed if I use console.log in that python.ts file I make the segfault more likely to happen.

    AapoAlas in deno discord helped me debugging this, it seems the root issue, is that when using PyCFunction_NewEx we're assuming struct will live long enough , but v8 does not know it should so it can be destroyed at any point.

    The fix is to extend its lifetime, the only obvious place to stick it in is PyObject, I can open a pr with this idea for review
