very cool! Have you also reported it upstream already?

FWIW

#gcc-4.6 test.c -Wall -Wextra -o test -O1 && ./test ; echo $?
0
#gcc-4.7 test.c -Wall -Wextra -o test -O1 && ./test ; echo $?
10

But -00 and -O2 produce the correct result with gcc-4.7 - maybe that's
why I was not able not reproduce this verbose issue with jack earlier
myself:

#gcc-4.7 test.c -Wall -Wextra -o test -O2 && ./test ; echo $?
0
#gcc-4.7 test.c -Wall -Wextra -o test -O0 && ./test ; echo $?
0

#gcc-4.7 --version
gcc-4.7 (Debian 4.7.0-8) 4.7.0
...

Cheers!
