After tracking, I found the problem is preg_replace function. I think you can replay this problem by the test code. 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. Actual result: -------------- This test code will cause apache error. You can confirm it in the apache error log. The browser display a connection error. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=50098&edit=1
