But it does occur if I start emacs with no .emacs, no .emacs.d, and no default.el. To reproduce: emacs C-x d ~/src/emacs/master [This is my clone of the emacs repo.] v [To view .dir-locals.el.] C-x v g At this point the cursor is in the annotate buffer (but not blinking), and emacs starts using a lot of CPU and is unresponsive. I assume it is inflooping. If I send the emacs process a SIGUSR2, it is responsive again. At this point I can do 'C-x v g' again with no problem. A bisection shows that the problem started with the following commit: commit 1431f667504b610471257802aa2f2f4f0d8443de Author: Eli Zaretskii Date: Sat Oct 17 15:10:58 2015 +0300 Avoid crashes when redisplayng a window changes faces or fonts * src/xdisp.c (redisplay_internal): If redisplaying the selected window or one of the frames turns on the frame's 'redisplay' flag, redisplay again. (Bug#21428) * src/frame.c (x_set_font): Set the frame's 'fonts_changed' flag.
