Description:
------------
if i use preg_replace function , my system log will show
Nov 12 13:41:31 mail kernel: pid 51185 (httpd), uid 80: exited on signal 4

i try to use ereg_replace, mb_ereg_replace function , it works . 

so I think it's preg_replace bugs.


$sql = preg_replace("/'(\\'|\\{2}|[^'])*'/", '', $sql)

sql statement is 
INSERT IGNORE INTO bb_posts_text (post_id, post_text) VALUES ( '117766', '?I!!?Q???@?~?e???L?e?]?ܱ`?W??mml???j?a???y???ɷӤ?

Please try using this CVS snapshot:

For Windows:

And also, you need to provide the full configure line you used to compile PHP. If you're using anything but bundled PCRE lib -> bogus.
