Hi Robert et all,

Ok details.  Now that I am able to compile/link/run using
that macro Jeff provided I can move on.

Quick summary, for legacy reasons we have a structure
called ByteArray passed around everywhere.  It is simply a
public class like this:
class ByteArray
{
public:
   unsigned char *pArray;
   int length;
   int offset;
}

On our receiving side we have a piece of code like this:

// The function argument(s) have to be like this
unfortunately.  Also pArray is serialized by the sender
with code like this but using binary_oarchive
OrderedCollection*
OrderedCollection::GetOrderedCollection(ByteArray *pArray) 
// this is a static method, pArray points to valid heap
memory
{
   OrderedCollection *pCollection = NULL;
   std::string astring  ((char*) (pArray->pData),
pArray->length + pArray->offset);

   std::istringstream iss(astring);
   boost::archive::binary_iarchive ia(iss);   // exception
here in Windows not Linux, below is the reason and call
stack
   is << BOOST_SERIALIZATION_NVP(pCollection);
   return pCollection;
}

Again this works in Linux, and I've run it through Valgrind
(a linux tool) with no errors or leaks.  If there is a
better way to construct a binary input archive I'd like to
know, im new to stl classes.

I get a std::bad_alloc exception, here is the call stack:
