Here is a C testcase:
```
struct a
{
  _Complex double j;
  double k;
  double l;
};

void b(struct a *__restrict c,
       struct a *__restrict  g,
       int e, double f)
{
  for(int i = 0; i < e; i++)
  {
        c[i].j  = g[i].j;
        c[i].l  = g[i].l;
        c[i].k = f;
  }
}
```

`-march=armv9-a -O3 ` is enough to reproduce it.
