These will give us the proper feedback on exactly what is causing the 
crash. I'm willing to bet ch->usrdata is 0x0, or is 0x3 or some such 
invalid mem address (caused by an overrun of some sort). If it is, you 
may want to insert an alloc_mem in the new_char_data() and the 
corresponding free_mem() in the free_char_data().
