Cannot reproduce.
Please make sure you've disabled all zend_extensions like Zend
Optimizer, APC, Xdebug, ionCube etc.

Do not file bugs when you have Zend extensions (zend_extension=)
loaded. Examples are Zend Optimizer, Zend Debugger, Turck MM Cache,
APC, Xdebug and ionCube loader. These extensions often modify engine
behavior which is not related to PHP itself.
