IE8 64b crashes when opening text file with bom

I created two plain text files containing some random data.
One of them had a byte order mark, another didn't.

When I open the file with bom, in IE8 then it displays files contents but
closing the window causes IE to crash. I noticed this kind of behaviour only
on 64bit IE8

I know utf-8 files should not contain bom but the target system that is
importing this format requires it and instead of saving the file, users may
as well open it directly with their browser.

You can download two sample files:
