Initial Comment:

Whec compiled with -Os the attached source causes avr-gcc 4.3.2 to throw in ICE.

The trigger is -fforward-propagate, the crash happens in pass .142r.fwprop1

Message:
This needs to be reported to the GCC project at:
http://gcc.gnu.org/bugzilla/

This is not a WinAVR bug. The WinAVR User Manual states that any potential
bugs in the GCC compiler must be reported to the GCC project and not here.

Closed as "Won't Fix."
