You have to check the apache error log to see the segfault. Of course if this type of code is in a function, the script will die inside the function. ------------------------------------------------------------------------ [2001-11-21 10:08:28] hegyvari@ardents.hu <? $str='1,2,3,4,5,6,7,8,9'; echo $str[0][NO]; echo $str[0][NO]; echo $str[0][NO]; echo $str[0][NO]; echo $str[0][NO]; echo $str[0][NO]; echo $str[0][NO]; echo "end."; ?> check http://mail.ardents.hu:701/info.php3 for a phpinfo(); This piece of code causes Apache to segfault. It is a distilled version, the original error was a typo inside a complex function, hidden inside a loop. It took more than a day to find. PHP4.0.5 produced the same result. ------------------------------------------------------------------------ Edit this bug report at http://bugs.php.net/?id=14161&edit=1
