That's very strange - a couple of questions:

After you run ./hello, can you recover the login?  ie is the system 
crashing, or is it just getting the terminal into a funny state?  Can 
you execute  "stty sane" (even if you can't see the characters as you 
type them)?

Does the same happen if you do an in-tree compile (basically create a 
uClinux-dist/user/hello diurectory, put your source and Makefile in 
there, and adjust the /user/Makefile to build your app)?

What if you do the out of tree compile, but remove the printf call (ie 
just have the program do effectively nothing)?

John
