Edit report at https://bugs.php.net/bug.php?id=69692&edit=1 ID: 69692 Updated by: danack@php.net Reported by: syl dot fabre at gmail dot com Summary: *** glibc detected *** php-fpm: pool www: corrupted double-linked list: 0x00000 -Status: Open +Status: Feedback Type: Bug Package: FPM related Operating System: Debian PHP Version: 5.4.41 Block user comment: N Private report: N New Comment: Thank you for taking the time to report a problem with PHP. Unfortunately you are not using a current version of PHP -- the problem might already be fixed. Please download a new PHP version from http://www.php.net/downloads.php If you are able to reproduce the bug with one of the latest versions of PHP, please change the PHP version on this bug report to the version you tested and change the status back to "Open". Again, thank you for your continued support of PHP. I believe this may be a duplicate of https://bugs.php.net/bug.php?id=69316 which is fixed, as the test script provided for this bug shows an issue on PHP 5.6.2 but not in PHP 5.6.7 However the version you are reporting it on, 5.4.41; that version is only receiving security updates now due to the PHP support lifecycle - http://php.net/supported-versions.php Please re-open this, or open a new issue, if you can reproduce this issue on a up-to-date version of PHP.

I can provide it if useful.
