Description:
------------
gmagick/1.1.2RC1
GraphicsMagick/1.3.18
PHP/5.4.16

All build from source, i can provide how the build was done on request.

--------------

On large operations to build different resized images from source images, sometimes the operation are aborted with this message:

php: magick/omp_data_view.c:181: AccessThreadViewData: Assertion `index < data_set->nviews' failed.
Aborted

The operation i do does not always gets aborted with this message, the last two tries running without any problems. I tried it now 5 times and 3 times it was aborted.

In my case i want to work on about 1600 different Images (formats and sizes).

Test script:
---------------
// Simplified script, the sizes for resizeimage() are calculated and ceil()'ed
$base = new Gmagick('abc.jpg');
$base->stripimage();


$result_image = $base->cloneImage();
$result_image = $result_image->resizeimage(800, 600, null, 0.9);
$result_image->commentimage('Add a 94 char long comment');
$result_image->setImageFormat('jpg');
$result_image->writeImage('abc_large.jpg');
$result_image->destroy();
unset($result_image);


$result_image = $base->cloneImage();
$result_image = $result_image->resizeimage(340, 255, null, 0.9);
$result_image->commentimage('Add a 94 char long comment');
$result_image->setImageFormat('jpg');
$result_image->writeImage('abc_expose.jpg');
$result_image->destroy();
unset($result_image);


$result_image = $base->cloneImage();
$result_image = $result_image->resizeimage(133, 100, null, 0.9);
$result_image->commentimage('Add a 94 char long comment');
$result_image->setImageFormat('jpg');
$result_image->writeImage('abc_thumb.jpg');
$result_image->destroy();
unset($result_image);


$result_image = $base->cloneImage();
$result_image = $result_image->resizeimage(100, 75, null, 0.9);
$result_image->commentimage('Add a 94 char long comment');
$result_image->setImageFormat('jpg');
$result_image->writeImage('abc_mini.jpg');
$result_image->destroy();
unset($result_image);


$base->destroy();
unset($base);


Actual result:
--------------
php: magick/omp_data_view.c:181: AccessThreadViewData: Assertion `index < data_set->nviews' failed.
Aborted

Forgot to mention it: It is a cli base php script.

Just tested the same script but switched to

imagick/3.1.0RC2
ImageMagick/6.8.6-7

and all running fine. Same files and amount of images.

The error appears to be happening in OpenMP.

Please try either using a version of GraphicsMagick that was compiled with OpenMP disabled, or try setting the number of threads that OpenMP uses to 1 via `Gmagick::setResourceLimit(5, 1)` or `Gmagick::setResourceLimit(\Gmagick::RESOURCETYPE_THREADS, 1)` for the latest version of Gmagick.

Short version, the OpenMP library is a good idea when it works, but when it doesn't work it is incredibly painful to figure out what the issue is.
