[avr-gcc-list] Bug in gcc version 3.0 20010605

[Andreas Schwarz]

Hello,

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
message:

avr-gcc -c -g -O3 -Wall -Wstrict-prototypes -Wa,-ahlms=gcctest7.lst -mmcu=at
90s2313 -I. gcctest7.c -o gcctest7.o

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).
