%%%--- Operating System, Graphics card ---

Ubuntu 13.04 amd64 + GeForce GTX 670
Windows 7 64bit + GeForce GT 650M

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

r60518, r60966 (own builds)
2.68a, 2.69 RC3 (official builds)

- Short description of error ---

Blender often crashes when using BI renderer and changing the 3D viewport to rendered mode (shift+Z).
It seems that changing the viewport from GLSL to Rendered after certain operation (e.g. undo) causes the crash.

Steps to reproduce:

Start Blender
Change the viewport to GLSL textured
Move the default cube
Undo previous step (ctrl+Z)
Change the viewport to rendered view

You should be able to crash Blender while repeating the steps 2-5 several times.
The step 3 above can be another operation such as changing the resolution in render settings.

Attached a backtrace that includes debug symbols (blender_rendered_view_crash.txt).

%%%I tried doing a bunch of things, but 3D view render seems to be stable here. The backtrace seems to indicate some material got corrupted, but I don't know why that would happen. There's not much I can do without more information.

Is this a new issue, or does it happen also in 2.68?
What are the actions before it crashes? When editing or removing materials or objects? Or immediately when enabling it?
Do you have a material or texture preview render open while starting the 3D view render?
Does this happen on the default cube, or is it only in some particular scenes?

%%%* I confirmed the same crash happens also in 2.68a. See blender.crash.txt.

It happens immediately after typing shift+Z.
I had the material preview, but I'm not sure if the crash can happen without the preview.
I didn't experience the crash on the default cube scene yet, but it happened on very simple scene (e.g. icosphere + monkey).

%%%Ok, it seems like I am going to need a .blend file and some steps to redo the problem, because I can't get it to crash. I spent a lot of time debugging this stuff for 2.68 and found no remaining crashes. So if it also happens in that version, it must be some particular setup or combination of steps that I can't guess well.%%%

This happened when I was using 2.69 RC3.

The crash happens again and again, about 5-20 times per day.

%%%The undo in the step 4 seems not essential. Changing viewport after some other operation sometimes causes the crash, too.

I confirmed GLSL view is not essential. Switching the viewport from "Solid" to "Rendered" also can cause the crash.

Undo seems to corrupt something.
