I can't reproduce this using a current build on macOS HS (either emacs-26 or
master), but I can with a prebuilt download from emacsformacosx.com. The
emacs-26 branch (dated 2018.01.23) and master (dated 2018.02.22) crash
every time. I don't know what system these were built on.

Here's a backtrace from 27.0.50, if it's useful:
