Operating system: Windows-10-10.0.22000-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 2080 with Max-Q Design/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 512.98

Blender Version
Broken: version: 3.3.0 Alpha, branch: master, commit date: 2022-07-22 03:59, hash: 087f27a52f
Worked:

Short description of error
Creating a cyclic graph in geometry nodes will hit an assert when using a debug build

Exact steps for others to reproduce the error
Create a cyclic graph like the following in geometry nodes while using a debug build. Any cyclic graph will cause a crash.

This does not appear to be an issue in the shader or compositor graphs.
