On purpose there is some kind of error in a compute shader. In the editor the error message is a bit "laconic". It should be more explicit and more helpful.

Error message:
Shader error in 'ErrorReportingFail.compute': Compute shader compilation had a problem, your compute shader was not compiled correctly.

Reproduced on 5.0 versions. On 5.1 such error doesn't appear.

Repso steps:
1. open attached project "ShaderErrorReporting.zip";
2. right click on "ErrorReportingFail" shader in project view and reimport it.
3. not informative message appears in the console.
