From: zhongxueming at gmail dot com Operating system: Windows XP, Windows Server 2003 PHP version: 5.2.11 PHP Bug Type: Scripting Engine problem Bug description: preg_replace cause Apache error and retart. Description: ------------ When I execute a sql by Zend DB, I got a connection error, and found an error in apache error log. After tracking, I found the problem is preg_replace function.

Env: Windows XP, Windows Server 2003 Apache 2.2.13 PHP php-5.2.11 Reproduce code: --------------- function testPregReplace() { $sql = "SELECT \"t_skill_label\".\"c_name\" FROM \"t_skill_label\" WHERE (\"c_name\" = '‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨‚ ‚¢‚¤‚¦‚¨') AND (\"c_id\" != '3') LIMIT 1"; echo preg_replace("/'(''|\\\\{2}|[^'])*'/", '', $sql); } testPregReplace(); Expected result: ---------------- Apache not be restarted.
