On Ubuntu 13.04, I did
$ PREFIX=$HOME/foo
$ mkdir $PREFIX
$ wget http://kegel.com/imagemagick/slow/slow.jpg
$ svn co https://www.imagemagick.org/subversion/ ... gick/trunk ImageMagick
$ cd ImageMagick
$ svn info
...
Revision: 13007
$ ./configure --prefix $PREFIX --with-modules --without-perl
$ make -j5
$ make install
$ PATH=$PREFIX/bin:$PATH
$ convert ../slow.jpg -depth 8 -auto-orient -strip -type TrueColorMatte -write PNG32:/tmp/img-conf.png '(' +clone -strip -resize 480x480 -write PNG32:/tmp/img-thumb.png +delete ')' -background 'rgba(255,255,255,.06)' -gravity center -resize 1920x1080 -extent 1920x1080 -write /tmp/img-slide.png -resize 480x270 -write /tmp/img-thumb-480x270.png -resize 160x90 /tmp/img-thumb-160x90.png
This crashed with
