I see. I need to use subregisters and the register scavenger together,  
so I have to do something. However, if a new and improved  
LiveVariables is forthcoming, I can simply disable certain assertions  
in the register scavenger in my local tree. That will create less than  
optimal code, but it will work.

I'll try to track down the premature kill in the coalescer. :-)
