I was incorrect about the issue source. `opDollar` is just called on a garbage:
---
struct S
{
    int x = 3;

    @disable this();

    this(int)
    { x = 7; }

    int opSlice(size_t, size_t)
    { return 0; }

    @property size_t opDollar()
    {
        assert(x == 7 || x == 3); // fails
        assert(x == 7);
        return 0;
    }
}

void main()
{
    auto x = S(0)[0 .. $];
}
---

As a result e.g. this will fail too:
---
import std.range;

void main()
{
    auto x = zip([1])[$ - 1];
}
---
