Hi, I've following class hierarchy: FilterCondition <---+--- CompositeCondition | +--- ConcreteCondition FilterCondition is ABC. FilterCondition has certain data members which I need to serialize. I already have another class "Table" for which serialization works perfectly. Now, I've added a pointer of type "FilterCondition" as a member to "Table". Say, the member name is "filterCond_". Now, as soon as I add following line in Table::serialize(), I get a crash : ar & filterCond_; This happens even though I make body of FilterCondition::serialize(), CompositeCondition::serialize() and ConcreteCondition::serialize() empty. In Table::serialize(), I've verified that filterCond_ is a valid pointer. I've declared FilterCondition as abstract through BOOST_CLASS_ABSTRACT macro as well.
