It happens both on x86 and x64 windows 7. I know that it is the Microsoft to blame, and it is a Microsoft based stack of technologies on backend of the site.
The question under question is quite nice, but I could only read it using google cache.
Confirmed -- it crashes in IE9 for me as well.
I've reported this to Microsoft (the report is here, if you have a Connect account).
Workaround for now is switching to IE8 (or even IE7) mode, the page loads fine in those (press F12 and choose "Document mode").
