Reduced test case

Reduced test case:

struct a {
 unsigned int a;
 unsigned int b;
};

struct a *const p = (struct a *)0x4A004100;

void bug50116(void)
{
 unsigned int i = 0;
 unsigned int *const x[] = {
  &p->a,
  &p->b,
  0
 };

 (*(volatile unsigned int *)((x[i])) = (unsigned int)((unsigned int)((*(volatile unsigned int *)(x[i])))));
}
