I believe this is the same problem reported in bug 34519.
The Debian build also fails with "diff: standard output: Broken pipe".

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.
