Hi Brice,
thank you very much for looking into this!
I am attaching the generated foo.xml.
I actually came across this error message when trying to play with OpenCL,
using the AMD SDK API. My main interest is in getting that to work on the
GPU, and that might still work on my current kernel (4.8), even if I get
warnings like the one reported.
