Here's a clearer testcase:

js> f = (function() { var x; if(0) { function x() {} } x; })
function () {
    var x;
    x;
}
js> eval("(" + f + ")")
function () {
    var x;
}

I get the same output for both cases now in comment #1.
js> f = (function() { var x; if(0) { function x() {} } x; })
(function () {var x;})
js> eval("(" + f + ")")
(function () {var x;})
