[Bug 590255] Re: php5-cgi crashed with SIGSEGV in zval_mark_grey()

Same here with 
Ubuntu Server 10.04, php 5.3.2-1ubuntu4.9
running a modified xtcommerce-shop.

The SIGSEGV happens at the end of the script (all output allready
written) every time it runs, no matter whether php5-cgi, php5 or cli.

No more Segfaults when zend.enable_gc=Off is set in php.ini.
