Hmmmm it looks as if the output from the printk() isn't making it to the 
screen when being run from a graphical terminal. You can tell this by 
pressing 't' (trace) when you run "bar" and it will return back to the 
Forth prompt. I'm not sure why this is the case at the moment.

Yeah - I've already found and fixed this one while I've been testing 
with -nographic on sparc64. Please try the revised v2 patch attached 
instead which should solve the issue for you.


ATB,
