Hi, I am using boost::serialization along with the eos::portable_archive (on Boost Vault). All the data that I serialize are polymorphic types, i.e. pointers. By experiment and days of frustration, I found out that the objects being serialized must "outlive" the archive or the serialization process -- otherwise I'd get segfault and corrupt data. I hope that was clear. To demonstrate this, I wrote a small example at http://boost.codepad.org/mqX5dUf6 (I'm a noob and I don't know the tradition to paste code -- should I just paste it in the message body or something?) The program will crash when you run it. However, if you comment out both the "delete" statements (leading to memory leaks, but at least the objects will outlive the archives), then everything works fine. Is there a way so that I can "flush" the serialization process so that it gets written immediately? The way that it is now, I must keep in memory all the things that I want to serialize. Thanks!
