-O2 problem / GCC 3.3.x

[Beschorner Daniel]

Any idea why results differ between -O and -O2 with GCC 3.3.x/Linux??? GCC
2.95 works fine.

results:
-O	500000
-O2	300000

Thanks
Daniel



#include <stdio.h>

int A,B,C;
int i;
int Q[1];

int H(int X, int Y)
{
        return X^Y^100000;
}

int main()
{
        A=B=C=100000;

        A+=H(B,C);
        C+=H(A,B);
        A+=H(B,C);
        C+=H(A,B);

        for (i=0;i<1;i++)
                Q[i] = 0;

        printf("%i\n",A);
        return 0;
}
