Reduced test case

Reduced test case:


void *A(const void *a);
void C(void);

static void B(unsigned short a[])
{
        long i, j, tmp;

        for(i = 0; i < 3; i++) {
                for(j = 1; j <= 3; j++)
                        tmp -= a[i - j];

                a[i] = (unsigned short)(tmp >> 1);
        }
}
void C(void)
{
        unsigned short a[3], b[3];
        B(b + 1);
        A(a);
}
