No, I didn't write any tests of non-subscripted arrays. My interpretation of the spec had been that they weren't allowed, but now that I'm re-reading it, I'm reconsidering. I'll investigate on the nVidia proprietary linux driver and let you know what I find out. Do you have Piglit tests for glGetTransformFeedbackVarying()? I was starting to write some, but it was slow going and I don't want to duplicate effort.
