ImageMagick 7.0.8-36 Q16 x64 HDRI on Windows 10.

This command produces no output image, no warnings, and no errors...

magick wizard: -virtual-pixel mirror ^
   -distort affine "0,640 0,640  480,640 480,640  0,0 480,0" wizard.png

Changing the virtual-pixel setting to anything other than "mirror" produces expected results.

On my Mac with IM 7.0.8.36 Q16, I get an abort trap for mirror and tile and its variant, but not for edge or random or dither or black.

magick wizard: -virtual-pixel mirror -distort affine "0,640 0,640  480,640 480,640  0,0 480,0" wizard.png

Abort trap: 6

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.
