| Thanks for reporting that. Although I don't have easy access to that
| platform, I simulated the problem on FreeBSD 11 x86-64 and came up
| with the attached patch, which I installed into the Emacs master
| branch. Please give it a try if you can, and let me know either way. I
| doubt whether this patch will apply to Emacs 25 and have not
| investigated the details there.
Tried your diff on Emacs 25.1, it segfaulted:
