# this is a tough one, I think I should explain # Zend use zend_object->properties_table both as zval ** and zval *** # if a zend_object->properties is not initialized, the properties_table is zval ** # while in rebuild_object_properties, zend will store the zval ** to zend_object->properties # then stash the zval ***(ie, zobj->properties_table[0] is zval ** now) to zobj->properties_table[0] # so when a zend_object inherit form multi parent and these parent have a same property_info->offset # properties, will result in a repeat zval **->zval ** transform, which will lead to a segmentfault # *may be* this fix is not the best fix, we should not use this tricky way, and rewrite this mechanism.

The same rules are applied for properties that are defined in the class hierarchy. Thus, if the properties are compatible, a notice is issued, if not a fatal error occures. (relevant with #60536)

Strict Standards: Notice and THello1 define the same property ($hello) in the composition of Notice. This might be incompatible, to improve maintainability consider using accessor methods in traits instead. Class was composed in %s on line %d

POST-CLASS-GUARD
|

Fatal error: TraitsTest and THello1 define the same property ($hello) in the composition of TraitsTest. However, the definition differs and is considered incompatible. Class was composed in %s on line %d
