Out of memory when filtering large sparse array

[middenview]

Problem occurs with a very large sparse array - first index value that is not undefined is in the millions.

With code of the form below, the debug statement never appears and an out of memory error is reported after a couple of minutes.

This may be a requirement of the language or a performance issue rather than a bug.

var res = this.sparse.filter(function(x,i,a)
{
logger.debug(x);
return (x.isLoggedOn && (x.smallArr.indexOf(groupId) != -1));
});

Try it in your Chrome / Chromium / Canary browser.
This should be reported at V8, not node

@middenview Although I can reproduce the issue, you should indeed report it to the v8 maintainers. See http://code.google.com/p/v8/issues/list.
