I did not update anything but ImageMagick, which anyway is not
compiled in Emacs, as it is version 7.

My system is not a distribution, and there are no automatic updates,
all tracking is in my head.

Yes, I can describe it.

Emacs is run as daemon by S6 supervision suite, through screen, as
below, nothing changed there since many months, this 2017 year.

I am connecting to emacs by the emacsclient, and the script below. I
had full stability until last 2 attempts to compile it with
ImageMagick, when I pulled last versions.

I am just about to try the one version before.

#!/bin/bash
SERVER=/home/data1/protected/tmp/emacs1001/server

if [ -e $SERVER ]; then
	if [ $DISPLAY  ];
	then exec emacs-client-x "$@" > /dev/null 2>&1 &
	else emacs-client "$@"; fi
else zile "$@";
fi
