When enabling OpenSubdiv, Blender just crashes with: [Error: EXCEPTION_ACCESS_VIOLATION] in the console
Steps to Reproduce: Open the included file, then enable [Use OpenSubdiv]
Sometimes it works by doing that but if you disable then re-enable OpenSubdiv a few times, it'll crash. It started (and often) crashing on my first try,
I think it crashes more frequently with new-depsgraph enabled but it also happens without it, so that's not a direct factor of the issue.
