No, I've deliberately *not* upgraded to Leopard until I am able to  
test CM3 on it.  Generally, I avoid bleeding edge OS upgrades for  
precisely this reason.  I don't know when I will have time to play  
with CM3 on Leopard.  Right now, I am tracking down another issue  
related to the regression framework Olaf is putting together.

At least this suggest your cm3 binary was able to run on Leopard,  
which is a good start.

I suspect that you need to rebuild the m3cg backend, but I have no  
idea how well it will play with Leopard.

Also, I have heard there were changes to ucontexts and other thread  
state which may mean M3 exceptions break, but I have not verified yet.
