To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report. ------------------------------------------------------------------------ [2015-01-30 09:24:58] sindrepm at gmail dot com Description: ------------ On a Magento web site I am getting the following segfault on both PHP 5.4.37 and PHP 5.5.20.
