I tried a v1.54 SVN 1018 Sandy Bridge executable (posted by ATH in February 2018) and had the same result that I posted earlier. I couldn't find a Sandy Bridge executable for SVN 1028.

So please give it a try, Rich.

The problem is with the .fb file. It's missing the top two terms. If you add them back in, then msieve will work:

Strange that. 11681692691969_17m1 is also an octic, and it is missing A7 and A8 in the .fb as well. Does NFS@Home use an older version of msieve?

Yes, r961. I believe the patch was added in r987. (thanks to jyb.)
