I think this testcase even better, it fails with -O1 -fstrict-aliasing and -O2:
struct S { int i; } s;
void f (struct S *q)
{
int a, *p;
p = &a;
if (q)
p = &q->i;
*p = 1;
}
void abo

I should note the better testcase is:
typedef __SIZE_TYPE__ size_t;
typedef struct {
size_t car;
size_t cdr;
} cons;
int g(void);
size_t f(size_t a)
{
size_t x;
size_t *d;
size_t i;
d = &x;
