I've noticed that ptr_container/clone_allocator.hpp contains an undocumented overload of new_clone that accepts a pointer-to-const:

I really don't see the problem, but removing it entirely is certainly an option.
Why do you get a compile error? Cloning is not supposed to require a mutable object. Is your problem with legacy code?
Because a pointer-to-nonconst argument binds to the new_clone overload that accepts a const reference (T is deduced to be a pointer type): template< class T > inline T* new_clone( const T& r ); This came up, because in implementing generic_ptr::cloning I wanted to make any wrapping pointer-like types available to the new_clone function, so I call it by passing a generic pointer-like object (sometimes an actual pointer) to new_clone (and provide suitable new_clone overloads) instead of passing a reference directly. This, for example, lets me lock any generic_ptr::monitor objects before their pointed-to object is cloned. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEARECAAYFAkp4LoUACgkQ5vihyNWuA4V2GgCfTfABLQOx27lZZgqQrVUCNLdn TNwAn1VVEfDy8XzjU2igdlF4pZRqL1ni =wDAd -----END PGP SIGNATURE-----
