Subject: bug#21745: 25.0.50; emacs infloops after call to vc-annotate
Date: Fri, 23 Oct 2015 15:14:50 -0400 [thread overview]
Message-ID: <562A872A.4030200@cornell.edu> (raw)
This bug does not occur in 'emacs -Q' or even 'emacs -q'. 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

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.
