First, get rid of that auto copyover.. Unless you want it. When the mud goes to save, what does ch->desc actually contain? (what's the address)
It sounds like something is stepping on it. We need to trace ch->desc as early as you can. Where is do_save called from? Start there, and trace it with GDB. If it's char_update you should insert some code to break on so as to not have to loop through all the mobiles.
