Godot Editor crash when referencing node in Autoloaded scene script.

[jeffgamedev]

Godot version

v4.0.beta5.official [89a33d2]

System information

Windows 10

Issue description

When referencing an onready node within the GDScript editor on a script attached to an autoloaded scene, the editor crashes.

Steps to reproduce

• Create an autoloaded Control scene.
• Add a child Control node.
• Create and attach a script to the autoloaded Control node that extends Control.
• Create an onready var that references the child node.
• Access the onready var child node via the GDScript editor in a method.
• Observe the editor crashes.

Minimal reproduction project

reference-test-crash.zip

In my reproduction project, simply open the "testui.gd", and in the _ready method, attempt to access the "test" control onready var. The editor crashes.

I noticed this right away in a larger project of mine after updating from beta 4 to beta 5, then created the minimal project.

Seems to be fixed on master, #67714 seems to have fixed this issue as I cannot reproduce.

Seems to be fixed on master, #67714 seems to have fixed this issue as I cannot reproduce.

I had high hopes for this being resolved from recent pull requests, but I just built from the top of master and the issue still occurs.

[jeffgamedev]

I was just able to recreate this issue on an entirely different Windows PC of mine on Windows 11 using the beta 5 editor.

I've just built the editor from the top of master and had the crash occur. I recreated the issue in the console editor application. Here is the stacktrace:

Trying to follow the instructions but it does not result into a crash on Linux x64. Is there something else to do?

[jeffgamedev]

Nope, that is where it crashes for me frequently: just after typing "test." Thanks for trying.

[TokisanGames]

Very likely the same as #68910, caused by #68663.

See #68910 (comment)

[akien-mga]

Presumably fixed by #68952.
