This is almost certainly the same bug as #24358. You can try building
with REL_ALLOC=no, or applying
https://debbugs.gnu.org/cgi/bugreport.cgi?msg=225;att=2;bug=24358;filename=v4-0002-Inhibit-buffer-relocation-during-regex-searches.patch.

That looks like the issue. I'll do a test build, and if successful, will add the patch to NixOS' emacs 25.1 build.

Thanks!
