System Information
Operating system: Linux-5.15.0-53-generic-x86_64-with-glibc2.35 64 Bits
Graphics card: NVIDIA GeForce RTX 2070 Super/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 520.61.05

Blender Version
Broken: version: 3.5.0 Alpha, branch: master, commit date: 2022-11-18 12:56, hash: 4e38771d5c
Worked: Latest nightly from Buildbot (blender-3.5.0-alpha+master.2c096f17a690-linux.x86_64-release)

Short description of error
Shift+D duplicating (certain?) shader nodes instantly closes Blender. A bit weird because some can be duplicated, others crash.

Exact steps for others to reproduce the error

  • Open the attached scene
    Node_Duplication_Crash_v01.blend
    It's a simple cube with a Principled shader plugged into a Mix shader and then into the Output:
    image.png
  • Shift+D to duplicate the Principled shader node -> Everything works as expected
  • Shift+D to duplicate the Mix shader -> crash

I loaded factory settings and can reliably crash Blender master. Latest Buildbot is fine.
I also compiled a Windows version (the original crash happened to me under Linux) and it also reliably fails on first try on a totally different system.

In how old version of the program can you reproduce it?

Buildbot build feels stable as I wrote above:

Can you check with this? {ab819517fc86}

Great, this seems to have fixed it.
