If MySQL segfaults, it's MySQLs problem and you should submit a bug to them. Since PHP and MySQL dont' share the same address space, there's nothing that PHP can do that can crash MySQL and have it be PHP's 'fault'. Previous Comments: ------------------------------------------------------------------------ [2004-05-27 17:20:07] tim at timcrider dot com PHP itself doesn't seg fault, it causes MySQL to seg fault. Do you need an strace of MySQL as well as PHP? The PHP file does not seg fault at all. It is MySQL seg faulting. The reason I believe this is a PHP issue, is that if I try to run the same query from the mysql monitor it works in both 4.0.20 and 4.1.1. However when I run that query from php 5.0.0RC2, with the wrong DB selected, it crashes MySQL, but the PHP script goes on just fine, all of the queries just fail. I hope this helps, if you have any other questions please let me know.

PHP continues to run fine, but MySQL crashes. Also, when trying to do this task inside of the mysql monitor and typing in the command with no database selected, it gives the standard: ERROR 1046: No Database Selected I have been able to reproduce this using MySQL 4.1.1 and MySQL 4.0.20. After installing both versions, I recompiled php to use those specific libararies. Reproduce code: --------------- mysql_query("LOAD DATA LOCAL INFILE '/usr/local/data_processor/.working/30953/ALL_SORTED.30953' INTO TABLE `tDWD31HTva`"); Expected result: ---------------- a mysql error, that does not seg fault MySQL. Actual result: -------------- MySQL Seg faults, no php error is produced, and MySQL doesn't log the crash as an error. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=28511&edit=1
