System Information
Operating system: Linux-5.19.0-46-generic-x86_64-with-glibc2.35 64 Bits, X11 UI
Graphics card: NVIDIA GeForce RTX 3060 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 525.105.17

Blender Version
Broken: version: 3.6.0, branch: blender-v3.6-release, commit date: 2023-06-27 08:08, hash: c7fc78b81ecb
Worked: (newest version of Blender that worked as expected)

Short description of error
Segmentation fault during rendering. It happens after some frames. Sometimes 5 sometimes 100. Heavy use of OSL shaders.
It might get triggered when using nautilus filebrowser and open the folder which contains the rendered frames during rendering. Just opening the folder seems to trigger the segmentation fault. Crash.txt file is empty.

Exact steps for others to reproduce the error
It happens when rending animation. I tried without GUI in comannd line and got the same error.
[Based on the default startup or an attached .blend file (as simple as possible)]

It's not very likely that opening nautilus caused the crash, the file system should handle r/w conflict.

From the description you seems to mean that the animation can crash itself after a few frames without intervention from outside? In that case it's likely problem of blender itself.

I rendered 100 frames (in reduced size) and it seems to be stable.

Sorry for the late reply and thanks for testing. I just rendered another file and have the same problem.
Running the animation works fine and rendering single frames is also no problem. but when i render the animation blender crashes after a few frames. only the segmentation fault error is shown in the console. nothing else.

It seems that the error only appears when I use OSL under Linux.

Could you share a crash log please? Thanks!

Unfortunately the crash log gives me only the Segmentation-Fault info. I tried to build Blender from scratch to get a more detailed error logging, but I failed so far because of missing packages on my system.
