Assuming you're using the IDE, check to see that runtime typing is enabled on the properties/C++ page of the project. Robert Ramey Paul Giaccone wrote:

Does the demo program demo.cpp http://boost.org/libs/serialization/example/demo.cpp have a bug in it?

When I run it, it crashes at the line that does the actual serialisation:

oa << s;

in save_schedule(), reporting the error:

Unhandled exception at 0x7c59bbf3 in SerializationDemo.exe: Microsoft C++ exception: __non_rtti_object @ 0x0012ee98

at line 260 of dbgheap.c:

pvBlk = _heap_alloc_dbg(nSize, nBlockUse, szFileName, nLine);

The call stack is

...

SerializationDemo.exe!_nh_malloc_dbg(unsigned int nSize=33, int nhFlag=1240696, int nBlockUse=5007849, const char * szFileName=0xe06d7363, int nLine=1) Line 260 + 0x15 C SerializationDemo.exe!malloc(unsigned int nSize=0) Line 139 + 0x15 C

I'm compiling in Windows 2000 using Visual .NET, if this helps.

PS: I modified the filename so it is correct for Windows (using backslashes) - it might be a good idea to use a boost::path here to make the code portable.
