I'm using g++ with GCC 4.8.1; when I use fprofile-generate too optimize my
code, it actually slows down the process time: (constant folding problem within
loop?)
int main(){
int n;

I found that only when I use very high vales for input the problem persists.
for example when using 123456 as input for profiling it generates incorrect
code but when using 12345 as input the correct code will be g

I further analyzed and found an interesting issue:
The optimizer bug (profile optimizer) occurs when input > 32768. When input is
less than or equal to 32768 (2^15) it always generate the correct optimized
code.
