Actually, AVR Studio's programming software is broken. Currently it 
writes the RAM init segment in its entire length but as the segment only 
contains enough data for .data it programs whatever there is in the ELF 
file after that segment to Flash. For me it has always been debug 
information. This is why I thought to suggest such a change in the first 
place.

Atmel has been notified and a fix should be in the next Studio, so it 
doesn't matter whether the change is made to AVR ELF files or not. I 
think that's more of a philosophical question on the interpretation of 
AVR ELF format.
