I can't reproduce the problem.
Rendered without crashing here.

Operating system: Windows-10-10.0.18941 64 Bits

Maybe the crash occurs only on Linux?

Hi,
I don't have any non-linux machine to test. But, for sure, thecrash
occured always in the selected render region only (not before, at least)
If it can help, my machines are both i7 4cores/8Threads, using
auto-detect threads and auto-tile add-on.

Thank you

Regards
François

its crashing for me,on linux (ubuntu 18.10),with blender 2.81.

The scene is exceeding a fixed max limit BVH_OSTACK_SIZE = 768

causing assert failure 'kernel_assert(stack_ptr < BVH_OSTACK_SIZE);'

i was able to render the full scene by subdividing the green ground plane mesh into 4x4 quads.

i thnk the bvh tree is crapping out because there is too many faces at one location + 1 larrge quad or something.

I had it crashing once, but I think that was for an unrelated reason, and I also cannot reproduce it anymore.

@Macroni can you reproduce that crash reliably or does it only happen sometimes?

@Fanfan At one point you wrote frame 450 in your initial post, is that a typo?

@JacquesLucke No, not a typo, It crashed also on this frame.
I don't have the laptop on which I discovered this crash anymore, I have a brand new computer, reinstalled from scratch, with Blender 2.80. I downloaded the attached file, opened it and pressed F12. It crashed. immediately (Scene 5, Frame 405, selected area). I tried to reopen, moved to scene 5, frame 450, removed the render area selection and pressed F12 : crash somewhere below the book in bookshelf "Le Misanthrope"

Crashes everytime for me on linux with 2.81a.
Splitting the single face of mesh 'Plane.000' into 4 quads fixes it for me.

However , blender-2.82-3e11c4e63b2f-linux-glibc217-x86_64 downloaded from https://builder.blender.org/download/
works fine.so maybe the bug is fixed in blender-2.82-3e11c4e63b2f

Can reliably make it crash in 2.81a as well, but current master or current builbot builds are fine...
(not aware of any specific commit that changed there, or if some default changed, but will assume this is resolved for good...)

@Fanfan , @Macroni : feel free to comment again if this creeps up another time...
