Reduced testcase:



typedef struct {

    float l, h;

} tFPinterval;



tFPinterval X[1024];

tFPinterval Y[1024];

tFPinterval Z[1024];



void Compute(void)

{

  int d;

  for (d= 0; d < 1024; d++)

    {

      Y[d].l= X[d].l + X[d].h;

      Y[d].h= Y[d].l;

      Z[d].l= X[d].l;

      Z[d].h= X[d].h;

    }

}
