--- Comment #2 from nixscripter at gmail.com ---
Correction on the steps to reproduce:

1. Get the current tree of ImageMagick from GitHub:
https://github.com/ImageMagick/ImageMagick

2. Compile it with OpenCL and HDRI support (--enable-opencl --enable-hdri
flags).

3. Create a JPEG image, and try to perform a simple Gaussian blur on it:

convert rose: input.jpg && convert input.jpg -blur 0x20 output.jpg

The blur does work for other image formats, strangely enough. Perhaps there is
a difference in data types?
