Slightly adjusted testcase:
int a;
union U0 { volatile unsigned f2, f4; };
volatile int b;
static union U0 c;
volatile unsigned d, f;
volatile int e, g, h, i, j, k, l, m, n, o, p;
int
main ()
{
a = b;
a += c.f2;
a += c.f4;
unsigned q = h;
a += q;
q = g;
a += q;
a += f;
q = e;
a += q;
a += d;
a += 2L;
a += j;
a += i;
a += k;
a += p;
a += o;
a += n;
a += m;
a += l;
return 0;
}
