[Boost-users] boost::serialization stream exception

Hi,

I encountered a mysterious stream exception when trying to deserialize 
an std::map<std::string,long> container. The exception seems to occur 
depending on the data stored in the container. Unfortunately none of the 
hints regarding stream exceptions from the manual seem to help.

The source code is as follows:

 >>>>

std::map<RHANDLE,long> ArchiveEntries;
...

void ResArchive::SaveToFile()
{	
        std::ofstream ofs (INDEX_FILE_NAME);
        boost::archive::binary_oarchive OArchive(ofs);
        OArchive <<ArchiveEntries;
}

void ResArchive::LoadFromFile()
{	
        std::ifstream ifs(INDEX_FILE_NAME);
        boost::archive::binary_iarchive IArchive(ifs);
        IArchive >>ArchiveEntries; //STREAM EXCEPTION!!!
}

<<<<

I do not open any file stream to the index file in any other part of my 
source code, so multiple simultaneous streams can't be the problem.

I can consistently reproduce the error for 2 given sets of test data, 
but I also have some test data ( just 2 entries instead of a few 
thousand) where the problem does not occur. I have not been able to 
isolate the exact data that is needed to cause such a stream exception 
though.

Any hints on how to proceed would be greatly appreciated. Thanks in 
advance for your time! :-)

Best Regards,
