Previous Comments: ------------------------------------------------------------------------ [2012-03-15 13:15:22] seth dot mos at dds dot nl Hi, Please find a full backtrace of the Segfault here. http://redmine.pfsense.org/attachments/download/557/php-gdb-full.txt Kind regards, Seth ------------------------------------------------------------------------ [2012-03-13 13:25:18] seth dot mos at dds dot nl I managed to get a core file and the output from truss. This is from a PHP with Suhosin, without Suhosin PHP does not core dump http://iserv.nl/files/pfsense/phpcore/ Not sure if that is enough. ------------------------------------------------------------------------ [2012-02-27 19:16:15] seth dot mos at dds dot nl Just confirmed that disabling the Suhosin extension in our PHP 5.3.10 build succesfully resolves the crash. We will take this up with the Suhosin maintainers. Kind regards, ------------------------------------------------------------------------ [2012-02-20 17:50:08] ras...@php.net I tried to reproduce this crash with the provided files on both Linux and FreeBSD and was unable to. We'll need more information. Could you get a backtrace for us? And second, could you try it without Suhosin enabled? ------------------------------------------------------------------------ [2012-02-20 13:11:28] seth dot mos at dds dot nl Description: ------------ Previously we used PHP 5.2.17 in pfSense 2.0 before we upgraded our build process to the current 5.3.10. We use the suplied xml to PHP array function in pfSense to convert RRD files and add new fields to RRD files. Here is the PHP version that we use on pfSense.
