Description

System Information
Operating system: Windows-10-10.0.19043-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3060 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 497.09

Blender Version
Broken: version: 3.0.0, branch: master, commit date: 2021-12-02 18:35, hash: rBf1cca3055776
Worked: not sure
Short description of error
I have a file with a simple Geometry Nodes modifier on a curve and extruding first vertex of a spline (based on direction) causes Blender to crash. It doesn't happen 100% of the time, but after a couple of extrudes it eventually crashes. Also it only happens if vertex has handle type set to Vector or spline type is Poly.

Exact steps for others to reproduce the error

  • Use the provided file
  • Extrude first vertex (one on the top in the viewport) on either of the curves
  • Repeat until Blender crashes
