I cannot imagine such a situation! Yes: if an object contains a pointer to one of its own data members, it will break if it's swapped under this scheme. (I do this frequently when an object can contain an arbitrary amount of information, but that info is *usually* small in size -- the pointer-to-data points to a small buffer which is part of the object itself.) -- Rob Macomber (rmacombe@u.arizona.edu) [ Send an empty e-mail to c++-help@netlab.cs.rpi.edu for info ] [ about comp.lang.c++.moderated.
