Godot errors when generating LOD for a too big GLB file

[ghost]

Godot version

4.1

System information

Godot v4.1.stable - Windows 10.0.19045 - Vulkan (Forward+) - dedicated NVIDIA GeForce RTX 2060 SUPER (NVIDIA; 31.0.15.3640) - Intel(R) Core(TM) i7-10700KF CPU @ 3.80GHz (16 Threads)

Issue description

When loading this GLB file, Godot crashes without any error message. (ZIP-ed for file size reasons.)

When loading Godot in debug mode, the following error is issued:

Vulkan API 1.3.242 - Forward+ - Using Vulkan Device #0: NVIDIA - NVIDIA GeForce RTX 2060 SUPER

ERROR: Condition "!_ptrnew" is true. Returning: ERR_OUT_OF_MEMORY
   at: resize (./core/templates/cowdata.h:297)

However, according to the resource monitor Godot doesn't consume anywhere near the 64 GB of RAM in this machine:

The GLB has 2.7M vertices, which loads without problems in other 3D engines.

Steps to reproduce

Drag the attached GLB file into any Godot project.

Minimal reproduction project

None necessary, but included here.

I haven't inspected the file yet, but when the byte count exceeds the 32 bit length limit godot fails to load the binary.

The file is ~100 MB, so that shouldn't be the case .

The crash is in the LOD generator. I opened a PR to replace the crash with a warning: #80467

Thank you @aaronfranke !
