Cycles crash

[mnhan32]

Compiled on Windows7 x64. OpenVDB modifier seems to work just fine. I was able to add OpenVDB modifier, preview, and see density value. However, Cycles crash every time I hit render, show preview, and add a new material, even in startup scene.

I got debug info with --debug-cycles
