System Information
Windows 7 Pro, 64 bit
Nvidia Geforce GTX 760 (updating the driver did not help)

Blender Version
Broken: 2.78a e8299c8

Short description of error
See attached blend file: Applied several modifiers to a cube, keyframed modifier properties. Animating the "Subdivisions" of a subsurf modifier leads to a crash of at least the graphics card driver and Blender, in some cases even of Windows 7, while rendering (GPU) the last frame (frame 81) with subdivisions of zero.

Exact steps for others to reproduce the error
Open attached blend file, render (GPU) frame 81

Cannot reproduce. Works for me on Linux.

Wild Guess: Is your graphics card is running out of memory?

Can't repro either, but given the scene is very slow to render, i'm guessing he hit the TDR timeout on his gfx driver, try rending with a smaller tile size.

Reducing the tile size was effective: 128 x 128 crashed as well, but 64 x 64 worked (render time 2:36:10.98).

I should mention that "graphics card driver crashes" means in this case that Windows reports that the driver needed to be restored after malfunction.

Yup, that's TDR in action :) If you still want to render with a larger tile size here's how to change or disable the timeout value (but naturally anything you do is at your own risk)

Thanks LazyDodo and Stephen.
@LazyDodo: I will read that TDR document, thank you for taking the time to post the link.
