Thanks for reporting this issue. I am able to duplicate the issue internally and will be reporting it to the correct team.
I'm also having this issue, albeit with an HD 7970 on Ubuntu 12.04 with Catalyst 12.8 & APP 2.7 - I'm getting this happening both in (some of) my own code (all of which compiles & runs fine on an Nvidia GTX-680 / Intel's OpenCL SDK), and also the example posted by oscezrcd
As this is a critical blocker for us, can you provide any information as to when we can expect a fix? Or even in more detail what exactly triggers this bug so that we can determine if it's feasible to work around it? - thanks.
