When I run revert-buffer-with-coding-system [RET] UTF-8 Emacs crashes.

This is the file I'm trying to revert.

I would like to know how to accomplish this operation without Emacs abruptly exiting. I'm working with GNU Emacs 26.1.

    Emacs should not crash. Consider filing a bug report: M-x report-emacs-bug. Include your file in the bug report, providing a recipe for the crash that starts with emacs -Q (no init file.). – Drew Sep 29 at 1:29
  • Indeed, just pasting this in a buffer triggered a segmentation fault in emacs 26.1, but not in 27.0.50. By the way, you mean revert-buffer-with-coding-system, don't you? – JeanPierre Sep 29 at 7:34
  • @JeanPierre Yes revert-buffer-with-coding-system is right. I'll change it in the question. – 9716278 Sep 29 at 8:45
