Can you walk me through it step-by-step? If you leave the assert alone, when does it fire? What set of insn_changes are being made when the assert fires? (Calling debug on the changes will show this.) And what use does the assert fire on? (Again, calling debug on the use will show this.) Thanks, Richard
