IM 6.9.8.4 Q16 Mac OSX Sierra.

Input:

Using this command and saving as PNG works fine:

convert x5hWF.png -negate -colorspace HSV -channel red -separate +channel -define histogram:unique-colors=false histogram:with_hist.png

But saving as GIF, creates an file that is not openable, i.e. corrupt

convert x5hWF.png -negate -colorspace HSV -channel red -separate +channel -define histogram:unique-colors=false histogram:with_hist.gif

It also fails the same way in IM 7.0.5.5 Q16

Thanks for the problem report. We can reproduce it and will have a patch to fix it in GIT master branch @ https://github.com/ImageMagick/ImageMagick later today. The patch will be available in the beta releases of ImageMagick @ http://www.imagemagick.org/download/beta/ by sometime tomorrow.

Thanks. This now works in the latest release today (6.9.8.5)
