System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: AMD Radeon RX 5700 XT ATI Technologies Inc. 4.5.14800 Core Profile Context 22.5.1 30.0.15021.11005

Blender Version
Broken: version: 3.2.0, branch: master, commit date: 2022-06-08 10:22, hash: e05e1e3691
Worked: 3.1

The problem is really similar to #93521, but in this case here, blender crashes once you use the curve to mesh node.

As example, you can use the same file as the one of the thread above, just add a curve to mesh curve in the end of the node tree and duplicate a single vertice, it will crash right after.image.png

Hi, thanks for the report. Can confirm in 3.2 but not in master build. Could you also check in 3.3? https://builder.blender.org/download/daily/
Which commit has fixed the crash is not known to me (neither mentioned in #98661).
I'll find the commit so we could also backport this to 3.2

I'm guessing that 2d80f814cc fixes this in 3.3. I suppose it could be backported, though it does change behavior in some cases.

@HooglyBoogly , you're right. Fixed with 2d80f814cc
So want me to list this commit for corrective release or you've any alternative fix?

I think you can go ahead and add it. It's a relatively simple commit and I don't think it has caused any problems in master. Thanks!
