Keeping state at "Feedback" until data requested by mafick is provided.

Yes, I will attempt to get this information to you. I can say that we were
using 5.2.13 without incident prior to updating to 5.3.8. After updating to
5.3.8, we were notified by users that they could no longer download files that
they were successfully uploading. That was when I determined the missing first
character. Because we didn't want to go backward, I put on the 5.4 version, and
the problem went away. Note that no changes were made in the PHP source during
the process of changing versions. I will try to back all that with the
requested data.

I've setup Apache 2.2.19 and PHP 5.3.8 (though not with mod_ssl) and have run
the test script you provided, but it doesn't produce the problem you reported
(it works fine).
In your report, $_FILES['filename']['name'] reports the length of the string as
10, even though only 9 characters are displayed.
Is it possible that somewhere in your program you're converting between
charsets or mangling the filename.
Also, could you provide a packet capture of the network traffic between your
web browser and your web application. You can do this with Wireshark
(Windows/Linux) or NetMon (Windows).

While I'm not enamored with the idea of running a beta in production, this
problem appears to be resolved in 5.4.0beta1-dev.

Description:
------------
After uploading a file using a multipart/form-data HTML form, the resulting
file name is missing the initial character (i.e. readme.txt becomes eadme.txt).
Server: Apache/2.2.19 (Win32) mod_ssl/2.2.19 OpenSSL/1.0.0d PHP/5.3.8
Test script:
---------------
<FORM ACTION="<? echo $_SERVER['PHP_SELF']; ?>" METHOD="POST"
ENCTYPE="multipart/form-data">
File: <INPUT TYPE="file" NAME="filename">
<INPUT TYPE="submit" VALUE="go">
</FORM>
<?
if (isset($_FILES)) {
var_dump($_FILES);
}
?>
array(1) { ["filename"]=> array(5) { ["name"]=> string(10) "eadme.txt"
["type"]=> string(10) "text/plain" ["tmp_name"]=> string(31)
"C:\temp\file_upload\php7D44.tmp" ["error"]=> int(0) ["size"]=> int(3420) } }
Expected result:
----------------
$_FILES['filename']['name'] should be intact rather than missing the first
character.
["name"]=> string(10) "readme.txt"
Actual result:
--------------
$_FILES['filename']['name'] is missing the first character:
["name"]=> string(10) "eadme.txt"
