System Information
Operating system: Windows 10 & Mac OS
Graphics card: Cycles CPU mode & GPU mode with GTX 1060

Blender Version
Broken: 2.80, Date: 2019-04-02 14:00, Hash: d986b04bd3
Worked: 2.79, 2.79b

Short description of error

I enabled OSL in Cycles and wrote a script simply calling diffuse_ramp(N, colors- [x]). Though it is displayed correctly in the viewport, it cannot be rendered. The same script works as expected in Blender 2.79. And the same problem does not occur for other closure functions (e.g., diffuse, oren_nayar, diffuse_toon...).

Exact steps for others to reproduce the error

Choose Cycles as render engine, and enable OSL.
Select any mesh, then in the Shader Editor, add and link the script node to the material surface output.
(The script and node configuration are attached.)
