The following input

```
void function(int) a;
void function(int) b;

void main()
{
    const c = *a == *b;
    // assert(*a); // rejected during sema
}     
```

crashes dmd in the backend:

> TYD func

> 0x00005555559d1756 in dmd.backend.cod3.jmpopcode(dmd.backend.el.elem*) ()

I think however that the program is semantically invalid and should be rejected during exp-semantics, just like the commented assertion is.
