dev-lang/php-5.2.8-r2 dev-php5/pecl-imagick-2.1.1 media-gfx/imagemagick-6.4.8.3 When performing Imagick::identifyImage() on a PDF loaded through Imagick:pingImage() a segmentation fault occurs. This only seems to happen with PDF files, and only when done with pingImage(). If readImage() is used instead, identifyImage() works as expected. This behavior changed between imagemagick 6.4.4.6 and 6.4.8.3. This segfaults all the time: php -r '$img = new Imagick(); $img->pingImage( "test.pdf" ); var_dump( $img->identifyImage() );' This works: php -r '$img = new Imagick(); $img->readImage( "test.pdf" ); var_dump( $img->identifyImage() );' As I do not have debug symbols I cannot give a backtrace, but do know that it is dying in ExportQuantumPixels() inside of the /lib/libMagickCore.so.1 library. I have tried removing imagick-2.1.1 and doing a direct pecl installation of imagick 2.2.1, which was released 2009-02-06, but that does not resolve the issue. Reverting to ImageMagick 6.4.4.6 does resolve the issue for me, but I don't wish to do this. To ensure that everything was clean, imagick and imagemagick were both uninstalled and reinstalled. This did not affect the issue.

Created attachment 183436 [details] My test.pdf file This is my testing file, which was created from Word 07 with the Save As PDF option.
Might be related to an old pecl-imagick version. Please retry with either 2.2.2 or 2.3.0_beta1 which I've just added to the tree.
