Casting to string makes the whole script fail in release build

[KoBeWi]

Godot version:
6f4384f

Steps to reproduce:

1. Add some Sprite node with a script
2. Put this code

func _ready() -> void:
	modulate = Color.red
	var a = 1.5
	var b = str(a)
	modulate = Color.blue

3. The sprite doesn't change color at all in release build

If you do var b = a it works fine.
Not sure about other conversions.

Most built-in functions can not be called in release build as there is a function call validation that requires information only available from DEBUG_ENABLED.

godot/modules/gdscript/gdscript_analyzer.cpp

Line 1854 in 07112b9

validate_call_arg(function_info, p_call);

validate_call_arg compares argument count and type, even without DEBUG_ENABLED. It gets information about the function to call from few lines above

godot/modules/gdscript/gdscript_analyzer.cpp

Line 1817 in 07112b9

MethodInfo function_info = GDScriptFunctions::get_info(builtin_function);

however get_info returns no information without DEBUG_ENABLED so comparing argument counts fails.

removing validate_call_arg from release builds solves the issue, but I do not know what kind of validations are still expected to run in release builds.

broken builtins have been reported here (#41706) but issue remained unresolved

Can't reproduce in https://downloads.tuxfamily.org/godotengine/testing/4.0/4.0-dev.20210727/

Here is a project with exports for Windows and Linux. (I couldn't export for macOS or some reason)
I tested Windows and it works just fine.

I'm looking for someone with Linux to test

I hope it helps!

Confirmed, it seems to work fine in 6882280.
