Visual C++ has a “Microsoft extension” that allows it to take a non-const reference to a temporary (and boost serialization uses non-const references whether you are serializing in or out).

If you compile with Microsoft extensions enabled: /Ze the following code will compile.
If you compile without Microsoft extensions enabled: /Za the following code will not compile.

struct obj_t{};

void foo( obj_t & );
obj_t bar();

void main()
{
    foo( bar() );
}

Thanks very much.  That is exactly what the problem was.  It used to work at one time though.  I think the C++ standard may have changed - or maybe it was in Visual C++ before I switched to a Linux environment.

many thanks.

The stream operator in Boost.Serialization does not take temporary
objects, so create the PersistentManagedArray<T> object on a separate
line, and then pass it to the stream.
