Description:
------------
When trying to detect the mime type of a specific file, the php-cgi.exe process crashes. It only happens with one specific .xls file I have. This .xls file does open in Excel without issues.

Test script:
---------------
// $filename is path to a specific file that causes the crash.
// I can't seem to upload this file here anywhere :(
$finfo = finfo_open(FILEINFO_MIME);
$mime = finfo_file($finfo, $filename); // CRASH
finfo_close($finfo);
echo $mime;

Expected result:
----------------
application/vnd.ms-excel; charset=binary

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32

Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.

In this case, more useful than a backtrace would be the Excel file that triggers it. Is is possible to share it?
