import std.stdio;

void main() {
    int i;
    writeln("Real &i: ", &i); // Prints 12FE44

    void nested() {
        writeln("Fake &i: ", &i); // Prints FFFFFFF0
        i = 0; // Access Violation
    }

    struct LocalS {
        // `S s;` or `S s = void;` fields also causes this bug
        // for `struct S { int unused = 0; }`
        int unused = 0;
        void f() { nested(); }
    }

    LocalS ls;
    ls.f();
}

Because of this bug things like `map!nestedPred("a b".splitter(" "))` give us
`Access Violation` so it's major.
