Description:
------------
Imagick::newImage() results in segmentation fault on 64 bit machines. The segfault only occurs on php-cli.

Details of my operating system, and relevant installed packages:

* Linux vgls66 2.6.34.10-0.6-xen #1 SMP x86_64 x86_64 x86_64 GNU/Linux
* Version: ImageMagick 6.6.1-0 2011-09-06 Q16 
* PECL extension: Imagick 3.0.1



Test script:
---------------
<?php

$img = new \Imagick();
$img->newImage(64, 96, new \ImagickPixel('black'));

// Segmentation fault

Expected result:
----------------
I'm expecting an Imagick object with the given dimensions, and a black background color.

Actual result:
--------------
Segmentation fault

Seems like a libmagickwand bug.

Limit Imagick to using only 1 thread.
Add this code before newImage:

$img->setResourceLimit(6, 1); // 6 means "limit threads to"

This is very likely to be an OpenMP related issue. Please set the thread limit to one, or recompile ImageMagick to not use OpenMP.

Limit Imagick to using only 1 thread resolves the issue.

As this is a bug in the underlying libraries, there is unfortunately nothing for us to fix here.

I'm going to add a bigger note about the thread setting to the next release of Imagick.
