gcc -o test.bin 2_1.cpp -w
test.bin
echo 127
127

Function main() must return 383, but return 127

cat 2_1.cpp
int main(){     
    unsigned x = 255, smallest, ripple, ones;
    smallest = x & -x;
    ripple = x + smallest;
    ones = x ^ ripple;
    ones = (ones >> 2) / smallest;
    return ripple | ones;
}

------- Comment #1 from falk at debian dot org  2006-02-06 10:04 -------
The return value of main() is interpreted in an implementation-defined way by
the
OS. Your OS (which you failed to mention) probably crops it to 7 bit. So this
is
not a gcc bug.
