Does the demo included with the library work?

I cannot serialize an object through a pointer.When running the program,it reports:
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
Below is the code :

I think maybe it's because I didn't build the serialize library correctly.I builded it with bjam.When debuging it with VS2003,an exception was thrown in the _heap_alloc_base (size_t) function at line 211:
line 211: return HeapAlloc(_crtheap, 0, size);
Function "void * __cdecl _heap_alloc_base (size_t size)" is in malloc.c.
