Yes. I think it helps as I think there are more places  in avr-gcc which 
requires changes. It can atleast track all the conversations happening on this 
bug.

AVR Toolchain is a gnu toolchain for 8- and 32-bit AVRs which is used by AVR 
Studio 4.18. Looks like the website was redesigned. I could find only 3.0.0 for 
now.

Register and install AVR Toolchain Installer. You cann see that the related 
patch  51-gcc-4.4.3-xmega-v14.patch modified __prologue_saves__ and 
__epilogue_restores__ functions. So this should solve the problem.
