The problem here is in mailparse. In mailparse.c:151, zend_register_internal_class is called but the return value is ignored. This function in PHP5 will always return a new object which should be used by the caller. In PHP4, it wasn't replaced so the address was ok. I will notify the maintainer of mailparse. Here is a patch to fix mailparse: 1 73c73 2 < static zend_class_entry mimemsg_class_entry; 3 --- 4 > static zend_class_entry *mimemsg_class_entry; 5 140a141,142 6 > zend_class_entry mmce; 7 > 8 148,149c150,151 9 < INIT_CLASS_ENTRY(mimemsg_class_entry, "mimemessage", mimemessage _methods); 10 < zend_register_internal_class (&mimemsg_class_entry TSRMLS_CC); 11 --- 12 > INIT_CLASS_ENTRY(mmce, "mimemessage", mimemessage_methods); 13 > mimemsg_class_entry = zend_register_internal_class(&mmce TSRMLS_ CC); 14 214c216 15 < object_init_ex(object, &mimemsg_class_entry); 16 --- 17 > object_init_ex(object, mimemsg_class_entry);
