System Information
Operating system: Windows-10-10.0.19044-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 516.93

Blender Version
Broken: version: 3.2.2, branch: master, commit date: 2022-08-02 18:15, hash: bcfdb14560
Worked: (newest version of Blender that worked as expected)

Short description of error
In a fairly simple geonode tree, trying to set lacunarity to 0 will crash Blender instantly.

Exact steps for others to reproduce the error

Use attached Blend.file
In the 'set position' branch, try to set 'musgrave texture' lacunarity to 0
Crashes everytime for me

Geonode attribute.blend

Changed status from 'Needs Triage' to: 'Confirmed'

Confirmed and the crash seems to be coming a bit downstream from Musgrave, the Attribute transfer node is having difficulty with that incoming data:

Oddly enough, if you unplug the Geometry input to that Attribute Transfer (down in the FENCE frame) and re-plug it, things seem fine...
