--- Comment #2 from Paul Backus <snarwin+bugzilla at gmail.com> ---
Reduced example:

---
void main()
{
    int[1] sa;
    int[] da = [0];
    sa = da; // equivalent: sa[] = da[]
    da = sa; // equivalent: da = sa[]
}
---

The assignments are allowed because of implicit slicing, so this is a subset of
issue 15932.
