Bug description:  zlib uncompress buffer error/ inflate failed

Hi,

the follow code produces a deflated string
which php can not inflate.


php results:
"Warning: gzinflate: buffer error in /web/htdocs/thisfile.php"

----
<tt>
<?php
error_reporting(63);
mt_srand ((double) microtime() * 1000000);

for ($original="",$i=0;$i<5000;$i++){
	//$original.=chr(mt_rand()); // 
	$original.="lala "; // problem
}

$packed=gzdeflate($original); // gzcompress
$unpacked=gzinflate($packed); // gzuncompress

echo "Length original:".strlen($original)."<br>";
echo "Length packed:".strlen($packed)."<br>";
echo "Length unpacked:".strlen($unpacked)."<br>";

if (strcmp($original,$unpacked)==0) echo "Strings are equal";
else echo "<b>Strings <u>not</u> equal</b>";
?>
</tt>
----


Regards,
