Description: ------------ A segfault always happen when running Imagine test suite (https://github.com/avalanche123/Imagine). This segfault happens when running gmagick driver tests, but are not reproducible outside test scope. I think it's not completely gmagick related as the backtrace reference PHP core calls as responsible of the segfault (see attached backtrace) This bug occurs with PHP 5.3.10, PHP 5.4.9, PHP 5.5.0-dev I can provide a dedicated debug box for this error. Test script: --------------- Running Imagine tests suite with gmagick extension 1.1.1.RC1 or 1.1.0.RC3 will produce the segfault (https://github.com/avalanche123/Imagine). Expected result: ---------------- No segmentation fault Actual result: -------------- Program received signal SIGSEGV, Segmentation fault. 0x000000000081e0c9 in zend_std_object_get_class

Hello Vito, Finally, here is a code snippet that reproduce the bug \o/ : --- beginning of snippet --- <?php class Image { private $gmagick; private $layers; public function __construct(\Gmagick $gmagick) { $this->gmagick = $gmagick; $this->layers = new Layers($this, $this->gmagick); } public function __destruct() { if (null !== $this->gmagick && $this->gmagick instanceof \Gmagick) { $this->gmagick->clear(); $this->gmagick->destroy(); } } public function histogram() { return array_map( function(\GmagickPixel $pixel) { return new \stdClass(); }, $this->gmagick->getimagehistogram() ); } } class Layers { private $image; private $resource; public function __construct(Image $image, \Gmagick $resource) { $this->image = $image; $this->resource = $resource; } } if (!file_exists('./google.png')) { echo "downloading the fixture ...\n"; file_put_contents('./google.png', file_get_contents('https://raw.github.com/avalanche123/Imagine/develop/tests/Ima gine/Fixtures/google.png')); echo "download complete\n"; } $image = new Image(new \Gmagick('./google.png')); // the same fixture must beloaded twice to reprodcue the seg fault $image = new Image(new \Gmagick('./google.png')); $image->histogram(); --- end of snippet --- I updated the title, as it seems that it is related to histogram despite the backtrace I gave.
