Comment 1 Tapani Pälli 2015-04-23 05:01:34 UTC 
I see, with GetActiveUniformsiv if error is generated, nothing should be written to output, not even for valid entries ... this is a terrible API :/ Will fix my implementation to have extra loop for verifying each uniform.
Comment 2 Tapani Pälli 2015-04-23 05:29:17 UTC 
I've filed a bug to Khronos about this. I don't think the expectation of the test matches the current specifications where GetActiveUniformsiv should match behavior of GetProgramResourceiv.
