--- Comment #2 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
another one:
// %3.1
typedef float real_t;

#define iterations 100000
#define LEN_1D 32000
#define LEN_2D 256
real_t a[LEN_1D];

int main ()
{

//    reductions
//    product reduction

    real_t prod;
    for (int nl = 0; nl < 10*iterations; nl++) {
        prod = (real_t)1.;
        for (int i = 0; i < LEN_1D; i++) {
            prod *= a[i];
        }
    }
    return prod > 0;
}
