Steps to reproduce the problem:
Compile and link the vertex and pixel shaders together in Chrome or Firefox.

Shader.html has both the sample shaders embedded and will compile and put output into 3rd textarea. All nice and neatly wrapped up :)

What is the expected behavior?
Successful compile and link.

What went wrong?
Link C:\fakepath(36,29-65): error X3003: redefinition of 'f_webgl_8148f64a6da52ff5'

Warning: D3D shader compilation failed with default flags. (ps_5_0)
 Retrying with skip validation
C:\fakepath(36,29-65): error X3003: redefinition of 'f_webgl_8148f64a6da52ff5'

Warning: D3D shader compilation failed with skip validation flags. (ps_5_0)
 Retrying with skip optimization

Failed to create D3D shaders.

Did this work before? No 

Does this work in other browsers? No
 Most likely an Angle bug, but I'm not very familiar with the entire Chrome/Mozilla/Angle/Microsoft ecosystem. There's a bunch of forks of Angle and I don't know which one is the right one.
