 New Comment:

A possible fix would be to raise the size of the memory allocated by
default, e.g. adding 1% to the length of the incoming data instead of
0.1% additionally to some "safe" padding bytes.

Description:
------------
Probably an edge case, but so nobody could claim I didn't report it ;) 
It starts to fail with ~200k+.


Reproduce code:
---------------
<?php

$j = 200000;
$s = '';

srand(time());
for ($i = 0; $i < $j; ++$i) {
        $s .= chr(rand(0,255));
}
gzencode($s); // fails with buffer error

$r = array();
echo "\nCharcode stats:\n";
for ($i = 0; $i < $j; ++$i) {
        $x = ord($s{$i});
        $r[$x] = isset($r[$x]) ? $r[$x]+1 : 1;
}
asort($r);
printf("MIN: %d -- AVG: %d -- MAX: %d\n", current($r),
array_sum($r)/count($r), end($r));

?>


Expected result:
----------------
No error

Actual result:
--------------
Warning: gzencode(): buffer error in
C:\Webserver\mike\zone\gzencode.php on line 10
