Sorry about being vague on the previous GCC versions--I didn't think it
mattered that much. I very well could have been using patches from Atmel back
then (it was a while ago). I cannot reproduce the problem today on vanilla GCC
4.3.5 and 4.4.6.
However I am able to reproduce the problem on 4.5.3 right now too (on a 64-bit
host).
