Yes, I do not see an error in yours code.
But there is a bit of differences:
  - main() is started with pushing r16,17,28,29 into stack
  - stack pointer is not loaded to SP ports, it is modifyed
All of this is absent in my disassembler result.

Are you use non-pure avr-gcc 4.1.1 ?

And can somebody to compile this example?
