Windows signals the program has generated a fatal error and will be shutdown. I had an array which looked something like this: $array[1][2][3] = 'value' and I used unset($array[1][2][3]) to clear the value of this element of my array. At some point in my script I accidently replaced the value of $array with a simple integer (e.g. $array = 'value'), so $array wasn't an array anymore. If i then tried to unset($array[1][2][3]), PHP would crash (after a few seconds of running @ 100% cpu). I know the code is faulty, I don't think it should be able to crash PHP... I'm using Apache 2.0.45 with PHP as a module, but the crash also occours when using the client version (php-cli.php on windows) from the command prompt. Note: The crash only occours when using multidimensional arrays. Reproduce code: --------------- <? $array = 'test'; unset($array["lvl1"]["lvl2"]["b"]); ?> Expected result: ---------------- When Using Apache: Windows signals apache has generated a fatal error and will be closed. Apache automatically restarts and resumes loading the webpage, thus crashing again and getting stuck in an endless crashing loop (until you close the browser). When Using PHP CLI: Windows signals PHP has generated a fatal error and will be closed, script execution is terminated and you are returned to the command prompt. Actual result: -------------- AppName: php.exe AppVer: 4.3.2.2 ModName: php4ts.dll ModVer: 4.3.2.2 Offset: 000cf358 I've also saved the log windows generated when the crash occoured. It's kinda long (in XML) and I don't know which (if any) part you require, so let me know if you need. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=24773&edit=1
