Hi Thorsten,

Thanks for getting back to me. Unless I'm missing something, the
examples indicate that a clone of an object is inserted when passed by
reference. Please see the example page here:

http://www.boost.org/libs/ptr_container/doc/examples.html#id6

--snip--
5. Objects are cloned before insertion, inserted pointers are owned by
the container
class X { ... };                     // assume 'X' is Clonable 
X x;                                 // and 'X' can be stack-allocated 
ptr_list<X> list; 
list.push_back( x );                 // clone 'x' and then insert the
resulting pointer 
--snip--

Best regards,
