Thanks to Brion Vibber, I learned that eAccelerator 0.9.5 is incompatible with PHP 5.2.1. (see https://www.eaccelerator.net/ticket/204 ) Turned it off by putting these lines in .htaccess: php_flag eaccelerator.enable 0 php_flag eaccelerator.optimizer 0 (see http://eaccelerator.net/wiki/Faq Usage)

Your server has a broken version of eAccelerator which doesn't work with PHP 5.2. It'll need to be upgraded.
