I have the same issue with PHP 5.3.0.

This makes the diff function unusable :(

Updating to latest 5.3 is a must, no matter if you see this bug or not.
 [2013-05-05 15:12 UTC] anka17pinky at yahoo dot com 
You mean 5.4.

Because this bug is present in 5.3.
5.4.3 seems ok though (didn't test others besides 5.3.0)
