System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 512.15

Blender Version
Broken: version: 3.3.1, branch: master, commit date: 2022-10-04 18:35, hash: b292cfe5a9
Worked: Blender 3.2

Short description of error
When I use the Generated value of a Texture Coordinate node, and have a modifier stack with an Armature above and a Subdivision below, it creates a really weird result broke.blend

Exact steps for others to reproduce the error

Check the .blend file and simply activate the Subdivision modifier on the model

Does disabling GPU subdivision in Preferences > Viewport > Subdivision fix the issue?
Does this happen for EEVEE and Cycles or Cycles only?
Might be related to #96596.

I can confirm it does fix it, and the issue is in both engines

Can you also try the latest daily build? https://builder.blender.org/
The issue is supposed to be fixed in 3.3 due to 342e12d6d9 and 3e25561d51. Maybe it is a different issue then.

I can confirm the problem.
In fact it only happens with GPU Subdivision.
It is seen in both Eevee and Cycles.
Interesting that if you disable and re-enable the Armature modifier, the problem is worked around.

I thought so at first as well, but then I noticed that the mesh wasn't actually subdivided in this state.
