stable 5.1 is released

Jani asked to *TRY* PHP5, not to install and use it instead of PHP4.
Please do so or tell that you're not interested in solution for your
problem. Thank you.

If you're not going to fix this and propose to use v5, please confirm
there will be no more updates for v4.x.

Please try using this CVS snapshot:

  http://snaps.php.net/php5-latest.tar.gz
 
For Windows:

Description:

hundreds of thousands of $a[]= ... and array_pop() calls triggers
memory overwrite.

Reproduce code:
---
?php

$a = array(0,1,2,3,4,5,6,7,8,9,10);

$paths = array();

$stack = array();
for($i=0; $i10; $i++) {
$steps = mt_rand(2,6);
// move forward
for($j=0; $j$steps; $j++) { $stack[] = array('x'=$a[$j]); }
$paths[] = $stack;
// move backward
for($j=0; $j$steps; $j++) { array_pop($stack); }
}

print_r($a);

?

Expected result:

array $a is never modified in the code, but when you print it at the
end of the script it spills out a whole lot of unexpected reccursions
or just dies with no output.
