System Information
Operating system: Linux-6.8.9-gentoo-x86_64-AMD_Ryzen_Threadripper_3970X_32-Core_Processor-with-glibc2.39 64 Bits, X11 UI
Graphics card: Quadro RTX 8000/PCIe/SSE2 NVIDIA Corporation 4.6.0 NVIDIA 550.78

Blender Version
Broken: version: 4.2.0 Alpha, branch: main, commit date: 2024-06-02 20:26, hash: 05f8d3565248
Worked: 4.2.0 hash: c3b985906d39

Short description of error
Cryptomatte node crashes the compositor when GPU is enabled.

Exact steps for others to reproduce the error
Load the attached file, go to the compositor and switch from CPU to GPU. It should crash without even having to render.

Alternatively (without the above file), just add a Cryptomatte node to the comp setup and toggle GPU compositor.

Can confirm. Here it crashed at glGenBuffers in GPU_context_create in RE_blender_gpu_context_ensure.

I just wanted to add that I can't reproduce this issue on my system. Although keep in mind that I am using a Mac with the Metal GPU backend, so there may be some differences there.

@ChengduLittleA Can you apply #122661 and see if it makes a difference?
