void takeADelegate(void delegate()) {}

void main()
{
    auto items = new int[1];
    items[0] = 17;
    foreach (ref item; items)
    {
        // both asserts fail
        assert(item == 17);
        assert(&item == items.ptr);

        takeADelegate({
            auto x = &item;
        });
    }
}

Hit this again. Raising priority, since it causes "mysterious crashes".

Looks like the same issue:
---
void main() {
    foreach(ref val; [3]) {
        auto del = { int j = val; };
        assert(&val != null); // Assertion failure
        assert(val == 3);
    }
}
---
and
---
void f(lazy int) { }

void main() {
    int i = 0;
    auto del = { int j = i; };

    foreach(ref val; [3]) {
        f(val);
        assert(&val != null); // Assertion failure
        assert(val == 3);
    }
}
