-Status: Open
+Status: Wont fix
Bug Type: Reproducible crash
Operating System: WinXP; Mandrake Linux 2.4.22-26
PHP Version: 4.3.7
New Comment:
This is a limitation in PHP 4 (elements can only have 2^16 references
too them), and is addressed in PHP 5. We will not fix this for PHP 4.

Description:
------------
In WinXP, crash occurs at $howmany >= 65537; in Mandrake Linux, crash
(specifying Segmentation fault) occurs at $howmany >= 131073. Note
that crash only occurs *after* all statements are performed.
I have been able to reproduce this everywhere, with any 4.3.2+ version
of PHP on all platforms, regardless of configuration or state of
php.ini.
Reproduce code:
---------------
<?php
$string = "X";
$howmany = 65537;
$b4guts = mktime();
$guts = array();
for ( $x = 0; $x < $howmany; $x++ ) {
$guts[$x] = $string;
}
$afterguts = mktime();
$gutstime = $afterguts - $b4guts;
echo "\nGuts built. Time $gutstime seconds. ", count($guts), "
elements\n";
?>
Expected result:
----------------
Normal program termination.
Actual result:
--------------
Windows generates a GPF requiring close of the process. Mandrake Linux
generates a "Segmentation fault".
