Tested versions

4.3.dev.custom_build.9adb7c7d1

System information

Ubuntu 22.04 CI

Issue description

When executing (this code was automatically minimized, so it is possible, that an even more "minimal" project can be created)

extends Node
func _process(delta):
	for i in get_children():
		i.queue_free()
	var temp_variable431 = Shader.new()
	temp_variable431.set_default_texture_parameter(StringName("127.0.0.1"), NoiseTexture2D.new(), -12)
	temp_variable431.set_code("2812479390")

This example was found by Godot fuzzer - Qarminer, so it is quite unlikelly that this code could be used in real project, but still this should be handled gracefully.

Memory leaks or asan backtraces are visible when using Godot build with sanitizers support - https://github.com/qarmin/GodotBuilds/actions (linux -> linux-editor-sanitizers)
