--- Comment #2 from Erik Verbruggen <Erik.Verbruggen at Me.com> ---
In the example program, the ifstream is not in binary mode. So, it will convert
\r\n to \n. So, when the preambles are compared for the unchanged case (where
the file comes from disk and contains \r\n line terminators) and the case with
unsaved files, they are of a different size because of the missing \r's. So
clang will re-generate the preamble.

So, it's not really a bug.
