This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org.  Please check that
the From: line contains a valid email address.  After a delay of up
to one day, you should receive an acknowledgment at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':

1) loaded attached file 'nelson.art' with ctrl-x f
2) emacs then proceeded to malloc all core, causing linux to grind to a halt.

Reproducable as the first command entered after emacs -Q.


If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file
/usr/share/emacs/24.3/etc/DEBUG.

commit a19bfb7 (HEAD, origin/emacs-26, emacs-26)
Date:   Tue Feb 19 22:04:19 2019 -0800

    Remove .art from the default list of ImageMagick extensions
    
    It seems that .art files can be non-image files that
    ImageMagick mistakenly treats as extremely large images.
    Real .art images seem rare.
    * lisp/image.el (imagemagick-enabled-types): Remove ART.  (Bug#22289)
