I tested on Linux & Android. Running in editor is fine. I definitely compiled new x11, android templates with latest source code.

Steps to reproduce:

1. type like this.

   
   extends Control

func _ready(): var n str(n)

2. export it
3. run exported game with **Debug ON**

**_Note that exported with release does not have this issue._**

**Minimal reproduction project:**

Running a project on Android with Godot, 1 commit before https://github.com/godotengine/godot/pull/19264, works fine. After compiling master and testing on Android, I get a similar error:

07-24 11:47:34.419 15303-15337/org.godotengine.jumpingdown E/godot: **SCRIPT ERROR**: Parse Error: Too many arguments for '()' call. Expected at most 0 but called with 3.

       At: main\main.cpp:1678:start() - Condition ' !scene ' is true. returned: false

BTW I changed gdscript_parser.cpp:6527 to get the arg_count

_set_error("Too many arguments for '" + callee_name + "()' call. Expected at most " + itos(arg_types.size()) + " but called with " + itos(arg_count) + ".", p_call->line); // Added arg_count to help debugging

BTW it is working fine in Windows and Linux. The error only happens in Android.

Similar problem also for windows export on version f8e8ac2.

Trying to export the multiplayer bomber demo project gives similar error messages for a debug export. Swapping all the str() calls with string interpolations did not solve the issue though. But might be related.

Minimal setup:

func _ready():
    #load gives critical errors in a export with debug
        #var world = load("res://world.tscn").instance()
    #with preload there is no issue in the export with debug
    var world = preload("res://world.tscn").instance()
    get_tree().get_root().call_deferred("add_child", world)

This script in the startup scene will cause a crash with the following error:

Also in this case, exporting with debug off seems to work fine.

@jahd2602 for me, exported apk with release works fine, but has above error with debug.
