Thanks for tracking that down. Frédéric's analysis in 
<https://bugs.debian.org/922552#19> was helpful.

I found some time to look into this bug, and installed into 
Savannah.gnu.org diffutils the attached patch, which I hope fixes the 
bug although I don't have the relevant platform to test it. Please give 
it a try.

Once this patch is part of a release, Debian shouldn't need any patches 
for diffutils.

For now I am closing the diffutils bug report 
<https://bugs.gnu.org/36488>; if I was too optimistic and the patch 
doesn't fix things we can always reopen it.
