Package: php4-imagick
Version: 0.9.11-0.1
I just done an "apt-get dist-upgrade", and now imagick functions crash PHP.
The source code was not modified.
It seems that PHP is now in ZTS mode, and before upgrade not.
The error msg in the Apache error_log : [Mon Mar 07 13:21:42 2005] [notice]
child pid 1215 exit signal Segmentation fault (11)
Debian : Sarge
Kernel : 2.6.8-2-k7-smp
Apache : apache2-mpm-prefork 2.0.53-5
PHP : php4 4.3.10-8
Imagick : libmagick6 6.0.6.2-2.1
(all are up to date Debian Sarge packets)
The PHP source code :
<?php

Your code works fine now that ZTS is disabled again.
