%%%--- Operating System, Graphics card ---
Windows 7, Geforce GTX 580 Classified (3GB)
Mac OSX 10.7, AMD Radeon HD 6750M (512MB)

- Blender version with error, and version that worked ---

2.68a, not an issue before with 2.67.

- Short description of error ---

After rendering a few times in a new window, pressing render will cause Blender to crash with no warning or error message. This happens in both the Windows 7 and Mac OSX versions of 2.68a; setting up two scenes in the Compositor with Linked Objects (in both Cycles and Internal).

- Steps for others to reproduce the error (preferably based on attached .blend file) ---

No way to replicate it with any specific action, just pressing render will cause it to crash on both platforms. Likely from the setup above.%%%

%%%Please attach a .blend file to demonstrate the issue? It's difficult for us to guess how you have set things up exactly.%%%

%%%I don't want to upload my work for everyone to have, however I could attach the crash log from OSX with details about Blender if that'll help.%%%

%%%@Dee-37 Grimm: remove objects, materials, nodes from your scene until you can still get a crash.
In this way you create a minimal file without your complete work and you also make it easier for developers to check where is the problem.%%%

%%%And please explain what you mean with "rendering a few times in new window"%%%

%%%What I mean is that the crash will randomly happen. It could crash once I press render, or after a couple of renders. There is also another related issue. If I cancel a render just as it's starting, whether I hit escape or close the window, it may also crash Blender in the same manner. I render two scenes, one from Internal for Freestyle and one in Cycles where I set all the materials. I think setting up these two scenes as RenderLayers is causing the issue since I never experienced this until I started doing this. If I remove one of the scenes, then the crash happens much less often, if at all, but I need the two scenes to render.

I don't want to make public my work, but if I could, I can email one of you the .blend file to test it out. I have a copy that always crashes on me within the first few renders, usually the very first one.%%%

%%%Dee if you can't reproduce the problem in a simpler file, can you build Blender yourself?
A backtrace from a debug build can help.
If you don't know how to do that, let us know if you can at least build blender and you can be instructed on how to get the backtrace.%%%

%%%Usually it's possible to simplify the .blend file until it has no value anymore except for bug fixing, for example by replacing meshes with cubes, removing materials and images, etc. That also helps identify the exact option that is causing the problem.

If it's not possible to simplify the file you can send it to me, at brecht@blender.org.%%%

%%%I emailed the file earlier today to Brecht.

I want to add that since I stopped rendering in a New Window, the crashing hasn't been an issue at all. I prefer a New Window, but I can continue by doing Full Screen instead. This is as far as I can narrow it down.%%%

%%%Thanks for the file, I could reproduce the crash.

Developer note: the cause of the crash is that apparently the render thread is messing with the editmode data which it shouldn't. A problem is that at the moment it can't detect this in BKE_object_handle_update, there's only the G.is_rendering which is not what we need. We actually need some sort of EvaluationContext that indicates if we evaluate for render, what the current time is, etc. I'll have to talk to Sergey since he's working on similar issues.

I suggest to move this there too?%%%

%%%Just quick update on this reports.

The issue is actually solved in my GSoC branch, but it might take some time to get all the changes backported to trunk. Think this is doable for 2.70. No chance getting this fixed for 2.69 since codebase is already frozen and fix requires quite a few design changes.

Marking report as READY now.%%%
