It happens here on Windows 8.1 64 bit on Nvidia GTX 650 4gb Nvidia driver 347.52
It can be that your pc motherboard has fried some capacitors (that means will crack in next year) or your videocard 3D engine it is burned.

Empty space of the modifier list anywhere under Vertex Weight Proximity space :)
With "Save Buffers" deselected I get only locking but it renders fine.
Without "Save Buffers" I get more aggressive locking of the whole pc but no crash.

Found the problem ... in this particular blend the render threads are set to fixed 64 yet I wonder why it crash ?
Does not crash if I save that particular blend with auto-detect (4 threads) instead of default 64
Happens on 32bit build 5aec61f and it is happening to build blender-2.71-81c3fc9-win64-vc9 , GPU CUDA render works perfectly , CPU crash.
Someone with Win 8.1 64 bit ... can check ?!

No gradient by default! +1
On the uploaded .blend file , I have opened it and to reproduce the bug , the steps are : -open the .blend (troll :P) - move the subsurfed sphere then press Tab then press Z (wireframe) , after that press Tab again to go to edit mode and Tab again , the subsurfed sphere will disapear.
Tested on my Laptop Radeon HD5650 1GB Core I7 Windows 8.1 64 bit
