Short description of error

No matter if GPU or CPU Render, Cycles crashes immediately with

Error: EXCEPTION_ACCESS_VIOLATION

Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps

I created a scene in Silo 2.3 64Bit and exported it as *.obj
Imported in blender, all seems well. Every object is there.
Then click on Cycles Render-crash

Blender or Luxrender Render seems to work.
Now I deleted ever object unless the problem-objects.
Still crash, please test it tester2.blend

Was crash log generated? Please upload if it does.

Also, try this:
It also worth running Blender with --debug-cycles command line argument to make prints much more verbose to see where exactly things stuck.

It is unclear for me how to reproduce the crash. opening the attached .blend file. It renders all fine.

The mesh object also seems to be a proper (at least it passes our validation).

So questions so far:

What are the steps of reproducing the error?
Does crash happen with latest builds from builder.blender.org?

@Blendify, i'm not sure why you removed BF Blender project here. The bug is reported to be happening during rendering, not during the import process.

@Wigand The file didn't crash for me, but I'm on Windows 7 / GTX 750.

Now it is the second bug I got with my GTX 1070. ( The first one: Unable to render volumetics #50808)
Is there still a problem with the card drivers? Should I contact NVIDIA?
What is the difference between Luxrender, Blender Render and Cycles - CUDA?

These objects use emission material together with a diffuse one.
As I remember, the mesh is a lathe, but maybe not closed, if you know what I mean.

The original scene has about 1600 objects and I deleted them until I found these rest with problems.

Do you need more information. Is there a way for me to get the debug info which procedure produces the Access Violation?

I checked these objects and tried to delete all their vertices with blender.
But some vertices are not deleteable!
But now, with these undeleteable vertices it is possible to render.tester2deleted.blend

So it is possible that this is an import problem, but why does cycles have problems with wrong meshes and blender render don't?

Please don't mix multiple reports into a single one, reports unrelated issues as separate reports. Otherwise things runs out of control quite quick.

I can not answer your question why Cycles crashes because i can not reproduce the issue.

So please:

Test the latest builds from builder.blender.org.
Test latest stable release (2.78c).
Provide exact steps reproducing the crash with the .blend file you've attached.

The latest stable release renders.

Sorry for the inconvenience

Thank you for helping.
