	Depens of your five lines program... if you're using printf you'll
end up using lots of functions inside libc... did you take a look at the
stripped object file, cause if there's an offset between 0 and the beginning
address of you program I think the default behavior of objcopy is to fill it
with zeros. Just open the .bin with an hex editor to make sure it is not the
case.

	Send your program to this list it will help for sure to understand
your problem
