Is there something we can do about serialization breaking between 5.0.xand
5.1.x? IIRC we don't save the PHP version number with serialized data. If
so, we could adjust the types according to version check.
Comments/ideas?

Modified files:
/ZendEngine2 zend.h zend_variables.c zend_variables.h
Log:
- Apply Thies and Sterling's patch which doesn't call ctor/dtor functions
- for types which don't require it (BOOL/NULL/LONG/DOUBLE)
- Breaks serialization!!!
