Is there any official way to get/substitute the index of the source-string that was passed to ShaderSource(...) in the log-string that gets
returned by GetShaderInfoLog? For some time I was able to rely on that Nvidia-drivers prefixed error-messages with "%SourceIndex(%LineNumber)"and ATI with "ERROR: %SourceIndex:%LineNumber". But suddenly all Errors-messages are prefixed with 0(%LineNumber) referring to some concatenated source that never was passed to gl in that way which makes finding the Point of error unnecessary difficult.
And by the way: Do other Vendor's Drivers produce similar Output?
