Looks like a GLSL compiler issue.

Right, now the examples works. Except gl-320-primitive-shading 

./build/release/gl-320-primitive-shading

You need to run it from the source root, like this: 
$ build/build/release/gl-320-primitive-shading

Otherwise it can't find/load the shader, and thats a shortcoming in the
samples, not Mesa.

I can confirm that I get the same assertion when running the original program,
see backtrace below:
