Bug description: Crash of PHP 4.3.x, having a big array
Description:
------------
Servus,
I got a crash of 4.3.x under Apache and direct call of php.exe under
windows, when the script creates a huge array.
When $nAmount has a value over 32768 PHP and Apache
crashes.
Any suggestions or help, how to get a better description of this problem.
Is it the same as following bug??
Bug #23872: reference to same variable(array) crash web server
Thanks,
Martin Brenn
Reproduce code:
---------------
...
<script language="php">
$nAmount = 100000;
$szPlayerID = 'x';
for ( $nCounter = 0; $nCounter < $nAmount; $nCounter++ )
{
echo ( $nCounter . "\r" );
$aszExtracted [ $szPlayerID ] [ $nUnit ] ['type' ] = $aszUnit [ 'type'
];
$aszExtracted [ $szPlayerID ] [ $nUnit ] [ 'job' ] = $aszUnit [ 'job'
];
$nUnit++;
}
</script>
..
Expected result:
----------------
No crash
Actual result:
--------------
Die Anweisung in "0x100b35ef" verweist auf Speicher in "0x000000008". Der
Vorgang "written" konnte nicht auf dem Speicher durchgef�hrt werden.
The command in 0x100b35ef refers to memory in 0x0000008. The operation
written couldn't be completed (or so).
My VC++ only reported these line, I don't have a debug build.
