    Possible bug in read_imagef


      Strange behavior - kernel works fine with this:

      __constant sampler_t imageSampler = CLK_NORMALIZED_COORDS_FALSE | CLK_ADDRESS_NONE | CLK_FILTER_NEAREST, using this - read_imagef(image, imageSampler, coords);


      without sampler and with "read_imagef(image, coords)" (should work the same way as above)  - data goes randomly crippled.

      An image is a 3D-image, referenced from OpenGL, rendered there slice by slice through FBO.

      Seems like a bug?

      P.S. Other regular 2D-image works fine with or without sampler.
