New issue 4091 by [email protected]: Wrong behavior regarding ECMAScript-6 generators
https://code.google.com/p/v8/issues/detail?id=4091

Chromium Version 41.0.2272.76 Built on Ubuntu 14.04, running on LinuxMint 17.1 (64-bit)
Also in "Node v0.12.2" with harmony flag enabled and Firefox 33.

Hello everybody,

I think (or at least I hope) the program below should output (as for example Traceur does, or in slightly different syntax Gorillascript and PHP 5.6 do):
"Open resource"
1
2
3
"Close resource"

Instead it outputs:
"Open resource"
1
2
3



=======
Program
=======

let generator = function* () {
    console.log("Open resource");

    try {
        yield 1;
        yield 2;
        yield 3;
        yield 4;
        yield 5;
     } finally {
        console.log("Close resource");
    }
}

for (let item of generator()) {
    console.log(item);

   if (item === 3) break;
}
