After I did some exception handling, it turned out that during serialization
some unregistered void cast was happening and that's causing stream error.
Probably debugger was pointing to wrong frame :(
After fixing those exception, crash is resolved. But I've new problem -
serialize doesn't write all data. And it seems the problem is because of
some ABC. Let me explain it here:
I've following class structure
A <--+-- B
|
+-- C
A is ABC and has no data member. B and C has data member. Some class D has
vector as data member. And my serialization code is something like
following:
D *dObj = D::instance();
oparchive << (const D&)(*dObj);
De-serialization code is something like following:
D::cleanup();
D *dObj = D::instance();
iparchive >> (*dObj);
I declare A as abstract through BOOST_IS_ABSTRACT. However, I also write an
empty serialize() for A.
Also, B and C serialization() uses base_object (*this). And B and C are
exported too.
Seems to me, the empty A::serialize() is causing the problem. But if I
remove it, the code doesn't compile unless I remove base_object (*this) from
B::serialize() and C::serialize().
I've verified that number of A objects in D after deserialization is same as
the number before serialization.
But those B or C objects (deserialised through A*) seems empty.
