Previous Comments: ------------------------------------------------------------------------ [2003-09-19 12:46:32] php at burnsystems dot de 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 durchgeführt 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.
