Bug 17663 – Wrong sequencing of argument list evaluation

• Component: JavaScriptCore
• Status: RESOLVED FIXED

[Maks Orlovich]

Per 11.2.3, the argument list is evaluate right after evaluating the 
function, and before checking whether the result is actually and object and callable. Hence, the following must print "hi":

<script>

function bad() {
    throw "hi";
}

try {
    var f = 42;
    f(bad());
} catch (e) {
    alert(e);
}
</script>


JSC evaluates the argument list later down in the sequence.

This was fixed by SquirrelFish, and I landed a test in r34413.
