Ahh, sorry for triggering this. It is a latent bug though. I am adding Jakub and Martin to CC - I do not know much how this is handled. If argument is fully replaced by constant we can represent that in debug info. If argument is removed and value is no longer computed, or it is aggregate and some of parts are dead, I think we have to resort to "optimized out". Honza
