Answers to your questions: a) it yields different behavior for the same archive. b) See attached source LegacyMonitorPersistentData.h c) See attached source PersistentData.h d) I have not tried that. I will give this a try. This is what I am testing. I have this archive file ^Press.dat. that was created once by our customer. I try to de-serializing using the loadPersistentData() function and it works sometimes, but about every third try it throw one of the exceptions.
Okay. What version of Boost are you using? Can you step through basic_binary_iarchive<Archive>::init() in a debugger? It's at boost/archive/impl/basic_binary_archive.ipp line 50. What you ought to see is: l is set to 22. file_signature is set to "serialization::archive" input_library_version is set to 5 "invalid signature" indicates that file_signature is wrong. Some info about the archive that you might want to verify: The platform is big-endian sizeof(size_t) == 4 sizeof(library_version_type) == 1. sizeof(int) == 4 sizeof(long) == 4 sizeof(float) == 4 sizeof(double) == 8 In Christ, Steven Watanabe
