Comment (by simonpj):

 Thanks.  I worked this through, and it turns out to be a dup of #10083.
 It was fixed by
 {{{
 commit 5a8fa2e662fce9ef03f0ec7891d7f81740e630bc
 Author: Edward Z. Yang <ezyang at cs.stanford.edu>
 Date:   Thu May 12 20:33:43 2016 -0700

     When a value Id comes from hi-boot, insert noinline. Fixes #10083.
 }}}

 For some reason, that fix never got merged to the 8.0 branch.

 I'm not sure if it's worth doing now.  There are workarounds described in
 #10083: can you use them in `hprotoc`?

 Simon
