I've also seen a bus error when one replaces the binary of a running program and it eventually pages in a page that doesn't match what's running; things that were previously aligned aren't any more, or a jump from the old code goes to the middle of an instruction in the new code. This is one of the reasons attempting to open() a running program's executable file for write returns ETXTBUSY.
