Infinite loop when calling .each() on a null element

Description
I noticed then when you call a jQuery('.unexistent-selector').each(function(){ ... do smthing ...}); generates an infinite loop.
I marked this as a bug, as I think this should not happen since the element does not exists in the DOM tree. I think it would be better to raise an "undefined" exception - so notice the user that the element(s) he wants to iterate through could't be found.

Using rwaldron's test case above, I haven't been able to replicate this issue either. There doesn't seem to be any evidence of an infinite loop occurring.
In addition, although there are a number of cases where we potentially could output an undefined exception internally, if you absolutely need this you could easily test for element existence prior to using $.each manually.
I cannot reproduce the error.

If you believe this is an incorrect assessment, please provide a reduced jsFiddle test case!
Additionally, test against the jQuery 0 GIT version to ensure the issue still exists.
