>Description:

imagick extension fails w/o preloading /lib/libthr.so.3
suhosin patch does not affect on this issue (tested with and without suhosin)


>How-To-Repeat:


Simple test script test.php:
<?php
$image = new imagick("test.png");
$image->cropThumbnailImage(50,50);
$image->writeImage("test_new.png");
?>


Without LD_PRELOAD:
php -f test.php
freezes w/o errors, test_new.png - not created.


With LD_PRELOAD:
LD_PRELOAD=/lib/libthr.so.3 php -f test.php
works fine w/o errors, test_new.png - successfully created
