System Information
Operating system: macOS-11.6.5-x86_64-i386-64bit 64 Bits
Graphics card: AMD Radeon R9 M295X OpenGL Engine ATI Technologies Inc. 4.1 ATI-4.6.21

Blender Version
Broken: version: 3.6.0 Alpha, branch: main, commit date: 2023-04-28 22:25, hash: 69d52c5f1c30
Also reproduced with 3.5 and 3.4.1

Short description of error
While using the Grease Pencil Line Art modifier, enabling the Light Contour feature causes a crash. The problem does not appear with a very simple scene, so a certain amount of geometry may be needed, hence the 6mb sample file. While trying to reproduce with smaller scenes, I sometimes had to toggle the Light Contour checkbox on and off a few times to trigger the crash, and the number of toggles actually varied from one launch to the next.

Exact steps for others to reproduce the error

Open provided file, GP crash.blend
Select Grease Pencil object and expand its Line Art modifier
Click Light Contour checkbox to enable it

This reliably causes a crash on my Intel Mac

Hi @jashear I couldn't quite replicate the crash. From my tests, it seems that it doesn't use much memory after all, so I don't think you ran out of memory.

Could you give us the crash log? https://docs.blender.org/manual/en/3.5/troubleshooting/crash.html Thanks!

Thanks for looking into this! I've attached a .crash file. Not sure if this is the same info that CrashReporter would provide, but the "Report" button in CrashReporter isn't doing anything, for some reason, so this is all I have.

Note that I'm using a 2014 Intel iMac with MacOS 11.6.5 (20G527), so not the latest and greatest anything.

@jashear Thanks! The log seems to indicate a threading issue. Could you please try running the same scene but start blender with blender -t 1 (here) ? Thanks!

@jashear Thanks! The log seems to indicate a threading issue. Could you please try running the same scene but start blender with `blender -t 1` ([here](https://docs.blender.org/manual/en/3.5/advanced/command_line/launch/macos.html)) ? Thanks!

@jashear Thanks for the info... Well then it's interesting, it could mean line art itself being not quite stable, I'll look into it.

@jashear : can you still get it to crash in frash builds from https://builder.blender.org/download/daily/ ?

Yes. I opened the file in today's 4.2 Alpha for Intel Mac, clicked the Light Contour checkbox, and it crashed.
