Operating system: MacOs Catalina

Blender Version
Broken: Blender 2.91.0 Alpha, August 21, 23:30:20- a1f54be042
Worked: 2.83

I have a scene where with heavy OSL use (materials with script) which was working nice in 2.83, but occasionally crashing blender in 2.91
I managed to track problem to script with raycasts, but failed to create small piece to reproduce this crash, on light scenes this works OK.
But on particular heavy scene crash is frequent //

There is a crash log from system, seems something related to OSL get message stuff blender_crash.txt
Hope this helps

by the way, i`m willing to help with such crashes, since i know it is really hard to track multythreading stuff down...
i have several random crashes in specific places (when localizing materials from library, for example) which reproducible on some scenes, but not always

Will it help if i will build debug version of blender and catch crashes from debugger? Will full xcode dump of such crashes help you?

Another thing to note - this always happens EXACTLY at the start of render of view_layer with sayed osl script. never in the middle of render, just at start.
seems like during/right after object synchronization
