Memory leak when declaring chans at the bottom of functions

[eholk]

The following program leaks c from main.

fn start(chan[chan[str]] c) {
    let port[str] p;

    p = port();
    c <| chan(p);
}

fn main() {
    let port[chan[str]] p = port();
    spawn start(chan(p));

    p |> c;
    auto c;
}

Interestingly, if you move the auto c; line above p |> c then the program works correctly.

A much simpler test case with the same failure is:

fn main() {
    x = @5;
    auto x;
}

I think the problem is that x is being zeroed out at "auto x".

(Well, actually the problem is that this is a valid program.)

marijn changed the scoping behavior so that these programs are no longer valid.
