[neko] crash on call with side effects after access of Dynamic Map

[Gama11]

On latest Haxe dev (a5d48bb) as well as 3.3.0-rc.1, the code snippet compiled to Neko crashes with:

Called from StringBuf::$statics line 1
Called from Main::main line 6
Called from A::clone line 18
Uncaught exception - Invalid field access : clone
Error: Command failed with error 1

On Haxe 3.2.1, it works fine, so it's a regression.

class Main {
    static var i:Int = 0;

    static function main() {
        var map:Map<String, Dynamic> = ["a" => new A(new B())];
        map.get("a").clone(i++);
    }
}

class A {
    public var b:B;

    public function new(b:B) {
        this.b = b;
    }

    public function clone(i:Int) {
        return new A(b.clone());
    }
}

class B {
    public function new() {}

    public function clone():B {
        return new B();
    }
}

I cannot seem to reproduce this particular error, though I do get one one the b.clone() for some reason.

Are you sure? I still get the exact same stacktrace on HEAD (8c3613e).
