Surface Shader with shader_features doesn´t compile

Shaders

-

To reproduce:
1. Open attached project;
2. Reimport shader "SurfaceBug".

Actual result: Shader doesn't compile, Editor is not responding when trying to reimport the Shader. If you end task (Unity Shader Compiler) in the Task Manager, Console throws errors:
-Shader compiler: internal error preprocessing shader: Protocol error - failed to read correct magic number;
-Shader error in 'SurfaceBug': Parse error: syntax error, unexpected $end, expecting TOK_SHADER at line 1.

    I hit this after updating some Microsoft stuff, nothing to do with Unity. The save as UTF-8 saved the day!

    VEGABEYOND, thanks I had a similar issue and encountered the 2nd error. Saving as UTF-8 fixed it.

    Well I tried to 'save as' the shader to UTF-8 instead of UTF-16 and it works... Just post here if helps anyone

    My new game-machine also took it's time parsing this. In the end it finished and produced this same error on 5.6.0f3

    Was having a very very similar issue, ended up just leaving unity compiling the shader, and tabbing out for about 10 minutes, it eventually compiled it fine!

    Might be worth giving that a go?
