Yep, I've been seeing this as well.  It looks like a basic block has been 
relocated and that the end marker has been changed to point to the 
addr*vec rather than the dispatch insn.  I haven't been able to track down 
exactly where this happens yet, except that it occurs after the gcse dump 
is made.
