Oh wait - I think I see what it is now. On closer inspection, it seems 
that translate was being invoked through CIF after all (I think now the 
Qemu output only shows blocks being translated and not executed?).

Tracing through the code, it seems like there's an off-by-one bug in the 
CIF parameter code which means that a subsequent stack push will 
overwrite the last saved parameter (which is %g7). I think I've fixed it 
and am testing a patch now.


ATB,

Mark.
