was seen on PHP 5.4.14 and on PHP 5.3.28
This bug can be solved by disabling garbage collection
in php.ini, set:
zend.enable_gc = Off
Then restart the webserver.
We cannot disable garbage collection as it would affect performance of Piwik.
You can set gc_enable to off if you experience this Segmentation Fault.
Please comment on this ticket and ask to reopen, if you experience the error "Segmentation fault" in archive.php script.
