[avr-gcc-list] Differences avr-gcc 3.4.3 vs 4.1.2

I have received a programming project where the original build was
done with avr-gcc 3.4.3. I am recompiling it using 4.1.2 (WinAVR
200770525) under cygwin. The compile runs very smooth without errors
or warnings, but the resulting code is not functional.

In order to track this down I need to understand more about the
differences between 3.4.3 and 4.1.2. Is this list the place to ask, or
should I also post to (generic) gcc lists?

Judging from the difference in functionality, I'm lead to guessing
that the problem lies in accessing two large tables that are stored in
program memory. Looking at the produced listing files from 3.4.3 and
4.1.2, organization of these tables had the most obvious differences.
But I'm far from ruling out that there are other causes.

I have source code and listing files from 3.4.3 and 4.1.2 available,
but don't want to flood the mailing list before knowing if this is the
right forum.
