Graphics card: NVIDIA GeForce RTX 4090/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 531.68

Blender Version
Broken: version: 3.2, 4.0.0 Alpha, branch: main, commit date: 2023-07-11 20:50, hash: c728fa0663b6
Worked: 3.1

Short description of error
When trying to sculpt a in an assigned collection that a grease pencil lineart modifier references and the layer it is drawing to contains Grease Pencil strokes - it will instantly crash Blender.

Exact steps for others to reproduce the error

Download and extract zip to get the test blend file
Load attached file with Load UI off
Select the bust, it is in a GP lineart modifier collection
Go to sculpt mode
Try sculpt
Crash

Alternative steps:

Create new scene
Create a sphere
Create a Grease Pencil object
Add sphere to a new collection
Select the GP object and add a lineart modifier
Reference the sphere collection in the modifier
Assign layer and material to the modifier
Draw in the same layer in Draw mode of the GP
switch to sculpt mode of GP object
Try sculpt GP object
Instant crash

Hi, thanks for the report. I can confirm the crash and assert hit in debug build (MEM_lockfree_mallocN_aligned at assert(alignment < 1024);)
This is a regression introduced between 3.1 - 3.2 release.
I'll raise the priority since it is easy to trigger the crash from default file.

@ChengduLittleA , maybe you're interested to investigate this?

I am actually unable to reproduce the issue with the provided file or from the steps using default file... I'm on linux right now. Will try windows, maybe the memory scheduling is different.

Any updates here? This is a high priority report and should be handled as such please.

Pratik Borhade commented

2023-10-06 11:01:06 +02:00

Not a recent regression so we can lower the priority I guess. I'll find responsible commit afterwards.

Nope not really reproducible here.

If it's memory related maybe it's due to the memory poll line art used, but internally it will ask for 1MB per chunk so the memory should still align, not really sure what's going on.

@ChengduLittleA , can you verify in uploaded file? :)

Seems so.

Ping, this is still marked as a high priority report. Either the priority should be lowered, or this should take precedence over other development.

I can't reproduce this crash in the 4.0 beta.

@filedescriptor , I assume you're on linux? (like Yiming)
I can still redo the crash in current main

@PratikPB2123 I built a debug build on windows for the current 4.0 beta and I can't get it to crash.
@AndresStephens Can you confirm this is still crashing for the 4.0 beta?

I can reproduce this now. Importantly, I needed to sculpt on the grease pencil object not the mesh (like the report says).
