Error loading jQuery 1.7 with Modernizr in IE8

[Issy]

I get (usually) an error when loading jQuery 1.7 with Modernizr in IE8:
Message: 'null' ist Null oder kein Objekt ('null' is null or no object)
Line: 1658
Character: 2
Code: 0
URI: ​http://ajax.googleapis.com/ajax/libs/jquery/1.7.0/jquery.js

My Modernizr example for jquery:

Modernizr.load([
	{
		load: '//ajax.googleapis.com/ajax/libs/jquery/1.7.0/jquery.js',
		complete: function () {
			if ( !window.jQuery ) {
				Modernizr.load('/js/libs/jquery-1.7.js');
			}
		}
	}
]);

jQuery 1.6.4 is loading without any error.

Thanks for taking the time to contribute to the jQuery project! Please provide a complete reduced test case on jsFiddle to help us assess your ticket.

Additionally, be sure to test against the jQuery Edge version to ensure the issue still exists. To get you started, use this boilerplate: ​http://jsfiddle.net/FrKyN/ Open the link and click to "Fork" (in the top menu) to get started.

Sorry, I can't reproduce it in jsFiddle. Anyway, it crashes after the block "Run fixed position tests at doc ready to avoid a crashrelated to the invisible body in IE8" at line 1658:

testElement.innerHTML = "";

5 lines before (line 1653) is it set to null:

testElement = container = null;

This is exactly my error message on IE7/IE8: 'null' is null or no object.

This looks to me a bit confusing.

Ok, I take a look at ​http://code.jquery.com/jquery-git.js and it seems to be corrected.

Duplicate of #10737.

I have the exact same error under IE8 (without Modernizr) but with jQuery loaded in a iframe if this can help.

Same issue. I use a home made script loader, perhaps this issue comes when jQuery is loaded dynamically by appending a new script tag...

I've had exactly the same thing using yepnope and IE7/IE8. I'm unsure as to what causes it. Updating jQuery to 1.7.1 fixed this error. Nothing obvious in the 1.7.1 changelog.
