--- Comment #3 from Rudolf Leitgeb <Rudolf.Leitgeb at gmx dot at> 2011-03-14 13:52:15 UTC --- Wow, it's a while since I reported this issue... and the problem seems to have gone away with newer versions of avr-gcc, I just tried version 4.3.5 which comes with Ubuntu 10.10. So, please go ahead and close it.
