You can crash Emacs for example with the recipe from #2099: $ emacs -Q --eval "(let (v) (while t (setq v (cons v v))))" In response to how such deep structures can arise: They may for example arise when testing Emacs with randomly generated code snippets. ... Emacs.pane.menubar.popup_*.File.Save (current buffer).fontList: 8x16 python-mode. top_level_run will perform all the expected modifications to the enviroment by the load of the .eln file. I am trying to install Emacs25 package on Ubuntu 16.04 alongside Emacs 24 and Emacs-snapshot (currently Emacs 27.0.50). To change the major mode from within emacs, press the M-x keys. The whole buffer can be reformatted with blacken-buffer.If you want to format every time you save, enable blacken-mode in relevant python buffers. I compile by running Make as you normally would through Emacs, except the compile command 1) rsync's the source tree to the remote build host and 2) SSH's there before running Make.
