Vray 3.5 Using OSL Glassshader stuck at merging LC

[Vizioen]

I was testing Rens' OSL glass shader and I wanted to see if it works with IPR. So I made a simple scene, 1 plane, 2 boxes and 1 vray plane. I used the osl on the plane and the 2 boxes and vrayplane a normal white vraymtl. Start IPR > Stuck at merging LC. Turns out it's not only with IPR it's with the regular renderer too.

Any ideas?

Would it be possible to attach the shader also, or to point us where we can download it from?
Thank you very much in advance.
