Comment 35 for bug 1677578

For Nish the minumum is really only:

# create test pic
char="y"; sz=16384; convert -size ${sz}x${sz} xc:white ${char}.png; ll -h ${char}.png

# Load and kill while that
<?php
    header("Content-Type: text/plain");
    ini_set('max_execution_time', 10);
    $image = new \Imagick(realpath('/usr/share/backgrounds/y.png'));
?>

I tested a 7.0.17 as requested but 7.0.17-2+deb.sury.org~xenial+1 did not change it.
