"-morphology thicken" in v7

This seems to be broken in v7. I use an example from http://www.imagemagick.org/Usage/morphology/#thicken

Input man.gif
Image

v6.9.9-50 (correct result):

Code: Select all

convert man.gif -morphology Thicken 3x1+2+0:1,0,0 mn_thk_v6.gif
Image

v7.0.7-28 (bad result):

Code: Select all

magick man.gif -morphology Thicken 3x1+2+0:1,0,0 mn_thk_v7.gif
Image
I can't see anything in http://www.imagemagick.org/script/porting.php that would explain this problem, but I might have missed something.

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 @ https://www.imagemagick.org/download/beta/ by sometime tomorrow.
