The flatten.php script, used to remove archived content object versions, is terminating with a segmentation fault.
The issue seems to occur after about 30 seconds, when the MySQL connection is closed, before any actual commit is done to the database.

Running the script with a test limit of 10 works without any issues, so it is possible that
the default portion size of 50 versions used in ZContentObjectVersion::removeVersions() is too high.
