Hi, I'm experiencing occasional problems with boost::serialization when trying to write then read two simple classes, to a file. I am using boost 1.33.1 Most of the time everything's working fine, but sometimes the serialized data seems to be corrupt and boost::archive throws an exception when I try to load it back into the program. The error occurs about about 1 in 10 times I try this, and seems to depend on the exact values of the variables being saved. Here's a call stack of the thrown application: WxNonogram.exe!_CxxThrowException(void * pExceptionObject=0x00129680, const _s__ThrowInfo * pThrowInfo=0x00ff4954) + 0x50 bytes C++ WxNonogram.exe!boost::throw_exception<boost::archive::archive_exception>(const boost::archive::archive_exception & e={...}) + 0x40 bytes C++ WxNonogram.exe!boost::archive::basic_binary_iprimitive<boost::archive::binary_iarchive,std::basic_istream<char,std::char_traits<char>
