> Intel driver bug. Reassigning it...
> =========
> **Answer from Darktable's OpenCL specialist Ulrich Pegelow:**
> Obviously the driver is not only nonfunctional for the hardware but contains
> a bug which triggers a SIGABRT. Nothing we can do here as long as this
> doesn't get fixed in the driver code. Only option is to run darktable with
> --disable-opencl as suggested in the manual.

> Does the driver need to be shipped with debugging enabled? With debugging
> disabled at least the assert statement will not cause the driver to
> terminate.
