PHP 5.1-200605011230 does work fine. Seems the area in question in
"ext/standard/pack.c" has been changed to:
if (argb > 0) {
len -= argb % 2;
}
Thank you Mike

Please try using this CVS snapshot:

For Windows:

Looks fine in 5.1.3.

Description:
------------
When unpacking hex with 'unpack', a "0" is appended to the end of the
resulting string. This did not happen in previous versions (this code
functions in PHP 5.1.1).
A quick fix can be done by commenting out line 695 in
"ext/standard/pack.c":
Change
len -= argb % 2;
to
//len -= argb % 2;
This line is one of 6 differences in "pack.c" between version 5.1.1 and
5.1.2. I wasn't able to understand why the "len -= argb %2" line was
added.
Reproduce code:
---------------
<?php
$HexString = 'c45dc988443fa8fff52ce7953bf049b8';
$PackedHexString = pack( "h*" , $HexString );
$UnpackedHex =
unpack( "h*Hex" , $PackedHexString );
$UnpackedHex = $UnpackedHex[ 'Hex' ];
echo "$HexString\n";
echo "$UnpackedHex\n";
?>
Expected result:
----------------
c45dc988443fa8fff52ce7953bf049b8
c45dc988443fa8fff52ce7953bf049b8
Actual result:
--------------
c45dc988443fa8fff52ce7953bf049b8
c45dc988443fa8fff52ce7953bf049b80
