[Boost-users] [Serialization - 1.35] Crash while serializing

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.

Following is top of stack from gdb:

Is this a bug in serialization library?
