System Information
Windows 10 64 bit, Build 10586
Intel Core i7-4710MQ (Intel HD Graphics 4600)
GTX 880m 8gig VRAM

Blender Version
Broken: (example: 2.69.7 4b206af, see splash screen)
Bug 1: Current master
Bug 2: Current master
Worked: (optional)
Bug 1: Don't know, oldest version I tested with was 2.74 and was broken.
Bug 2: 2.76b

Short description of error
Bug 1: The magic texture has no Fac when using OSL, but does work with SVM.
Error message in console when connecting a Fac output with a input of a another node:
"ERROR: ConnectShaders: "Fac" is not a parameter or global of layer "node_magic_texture_00000201AF660CB0" (shader "node_magic_texture")
ERROR: ConnectShaders: cannot connect a unknown (Fac) to a float (Val), invalid connection"
patch for Bug 1: patch.diff

Bug 2: The result of Fac by the Voronoi texture is different between OSL and SVM. Just connect a Voronoi Texture node with his Fac to a Diffuse Shader node and switch between OSL and SVM shading. Render results will be different. It occurs with both methods "Intensity" and "Cells"

Exact steps for others to reproduce the error
See above

Thanks for the report, fixed the issue now. I could not see any render difference though.

Bug 2 is indeed still present, was assuming this happens in Magic texture falsely. :/

That’s an OSL bug according to http://lists.blender.org/pipermail/bf-committers/2016-February/046604.html

Closing as solved for now, we can always reopen should the bug persists after all platforms have been updated.

Also, @mageoftheforest please only report one issue per bug, otherwise it’s harder to track what’s actually fixed!
