Still segfault with PHP 4.3.10RC2 and PCRE Library Version 4.5 01-December-2003 Previous Comments: ------------------------------------------------------------------------ [2004-12-06 16:17:35] [EMAIL PROTECTED] Can't reproduce with any of dev versions (tried latest 4.3.10-dev, 5.1.0-dev & 5.0.3-dev under Linux). Please, try latest snapshots and tell me what version of pcre you're using (mine is 3.9) if you're still able to reproduce it. ------------------------------------------------------------------------ [2004-09-28 10:41:22] xanthor at xanthor dot tk The regexs still crash PHP 4.3.9 and PHP 5.0.2 ------------------------------------------------------------------------ [2004-09-16 15:50:47] [EMAIL PROTECTED] your last regex crashes PHP 5 also. The segfault isn't in PHP but in pcre (this is quite normal due to the NFA nature of pcre). ------------------------------------------------------------------------ [2004-09-10 17:01:41] hewei at ied dot org dot cn preg_match("/(((?<!aaa).)*)(?<!aaa)aaa/",str_repeat(' ',10882).'aaa',$z); crashes PHP4.3.9RC2 But not on php-4.3.2-11.1.ent (WBEL 3.0), the length to trigger segmentation fault is about 19230. The most funny thing is that the more closer to the limit, the more likely you will get a random segmentation fault. Not only the above pattern will cause the error, preg_match("/^( )*$/",str_repeat(' ',19250)); will too. ------------------------------------------------------------------------ [2004-09-10 12:49:48] [EMAIL PROTECTED] Please try using this CVS snapshot: http://snaps.php.net/php5-STABLE-latest.tar.gz For Windows: http://snaps.php.net/win32/php5.0-win32-latest.zip I couldn't reproduce any of the crashes. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
