From: Sean McAfee <smcafee <at> sungevity.com> To: bug-gnu-emacs <at> gnu.org Subject: 25.0.50; exiting ediff can leave Emacs unresponsive to keyboard input Date: Fri, 30 Oct 2015 17:02:24 -0700
Recipe: 1. Start graphical Emacs with emacs -Q. 2. Create a buffer named "foo" with C-x b foo RET; insert the text "foo\n" there. 3. Create a second buffer named "bar" with C-x 4 b bar RET; insert the text "bar\n" there. 4. M-x ediff-buffers foo RET bar RET 5. Either exit Ediff immediately with q, or move around and past the single difference region with n's and p's, then exit. With an appreciable frequency, after these steps Emacs is left in a state in which it ignores any further keyboard input. Mouse interactions are unaffected, but not particularly useful with no more keyboard input registering. I have to close Emacs and restart, but if Emacs asks me any questions before closing (eg. if I want to save any modified files, or exit despite some processes still running), I'm stuck; I cannot respond, so I have to open a terminal and kill the Emacs process. The same thing can happen if I use ediff-files instead of ediff-buffers. The issue does not seem to arise if Emacs is run in non-graphical mode, ie. by "emacs -Q -nw".
