Hi Thies,
thank you for your changes in zlib.c but you have not
really fix the problem.
If i increase the string repeating from 5000 to 35000,
i have the same problem again, but
i don't no why, sometimes php works correct...
<---snip--->
<tt>
<?php
error_reporting(63);
mt_srand ((double) microtime() * 1000000);
for ($original="",$i=0;$i<35000;$i++){
//$out.=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>

fixed in CVS
you can make it work in 4.0.6 by changing maxfactor from 8
to lets say 16 in zlib.c around line 912

Hi,
the follow code produces a deflated string
which php can not inflate.
php results:
"Warning: gzinflate: buffer error in /web/htdocs/thisfile.php"
