Custom Class Constructor 'new' not found only in release exports

[CorbinSteele]

Godot version

v4.1.stable.official [9704596]

System information

Godot v4.1.stable - Linux Mint 19.1 (Tessa) - Vulkan (Compatibility)

Issue description

The code var constructor : Callable = CustomClass.new works exactly as expected in the editor and in debug exports.

In release exports however, this causes:
SCRIPT ERROR: Parse Error: Cannot find member "new" in base "CustomClass".

This error seems to always occur regardless of what CustomClass extends, and regardless of whether _init is defined.

WORKAROUND:
Wrapping every constructor callable in func(): return CustomClass.new() solves this issue, but is annoying and shouldn't be something discovered only upon attempting a release export.

Steps to reproduce

This is very simple to reproduce, but I created a reproduction project anyway just in case something weird is going on with the default Linux export presets.
Running it in the editor or after exporting it as a debug export will print SUCCESS.
Exporting it as a release export and running it will print FAILED and make the error apparent (if run from console).

This also happened on my project. Using Godot 4.2.1, Windows

Thank you so much for the workaround!!

Hopefully this will be fixed soon, just as you mentioned, this only happened in the release version.

I still get this error, when exporting without debug. I tried with 4.2 and commit e761982979fa3953ce7dd28c2337e7ae81ca5630 as cherry-pick, but also on master.

In my case I pass the new function as a callable argument to a function:
create_obj_and_do_something(MyClass.new)
