I think have found a Bug in the gcc-version from www.combio.de/avr/.
When I try to compile the attached program, I get the following error

avr-gcc -c -g -O3 -Wall -Wstrict-prototypes -Wa,-ahlms=gcctest7.lst -mmcu=at
90s2313 -I. gcctest7.c -o gcctest7.o
gcctest7.c: In function `main':
gcctest7.c:120: Unrecognizable insn:
(insn 320 317 321 (parallel[
            (set (reg:HI 66)
                        (mem:BLK (reg/f:HI 64) 0)
                        (const_int 0 [0x0])
                        (const_int 1 [0x1])
                    ]  0))
        ] ) -1 (nil)
gcctest7.c:120: Internal compiler error in extract_insn, at recog.c:2210
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
make: *** [gcctest7.o] Error 1

It works only when I turn off optimization completely (-O0).
