Hi Andrew

I would like to give some feedback to what you originally asked Steve:

Did you check on OS X?

On GNU/Linux I never saw the issue, on OS X regularly under certain
circumstances which are not clear to me. With the recipe of Steve I
can reproduce on build GNU Emacs 25.1.50.1 (x86_64-apple-darwin13.4.0,
NS appkit-1265.21 Version 10.9.5 (Build 13F1507)) from
