I checked in a change (revision 6163) to Zend_Db_Statement that broke handling of parameters in the execute() method in PDO adapters.
I'm working on a fix which I will check in promptly, but I just wanted folks to know that I'm aware of the problem and working on it. So if you normally update ZF from the head of the subversion tree, don't update past revision 6162 until I do my repairs. My apologies! Bill Karwin
