propHooks failing in IE9 under non-minified 1.9.1

[scottm@…]

Line 2631 of the non-minified 1.9.1 fails with an exception under IE9 when it attempts to perform a getAttribute on an object that does not have a getAttribute method:

jQuery.each([ "href", "src" ], function( i, name ) {

jQuery.propHooks[ name ] = {

get: function( elem ) { return elem.getAttribute( name, 4 );

However, the minified version of 1.9.1 does NOT fail this way. Looking at the minified code, it appears that it has a try/catch wrapped around the code, which catches the error:

i.propHooks[t]={get:function(n){var i=null;try{i=n.getAttribute(t,2)}catch(r){}return i}}

It appears that the minified code is still using the "4" flag instead of the "2" flag as specified in jQuery bug 10299.

Aren't the minified and the non-minified versions supposed to be identical?

The non-minified version of the code should be corrected like the minified version in order to fix this bug.

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—you may need to change this to a specific version depending on the test case.

I have absolutely no idea how to recreate this problem outside of the large application use case in which I originally encountered it.

What I do know is that as I mentioned, the error occurs only in the non-minified code, and that upon examination, the minified code is functionally different than the non-minified code. The minified version of the code has error handling in the routine in question, while the non-minified version does not. I'm pretty sure this isn't the way it's supposed to be.

Can you confirm that your files are exact copies of the ones on code.jquery.com? Doesn't seem so from your description.
