ID: 19386 Comment by: [EMAIL PROTECTED] Reported By: [EMAIL PROTECTED] Status: Open Bug Type: PCRE related Operating System: * PHP Version: 4.2.3, 4.3.0-dev New Comment:
I cannot reproduce this bug using the latest cvs on redhat 7.3. The script just keeps going. I cut it off after 20000 chars. I also do not experience this problem with the latest cvs release on FreeBSD 4.6-STABLE. Devon Previous Comments: ------------------------------------------------------------------------ [2002-09-17 08:07:05] [EMAIL PROTECTED] I've reproduced this using the php4-win32-latest snapshot. The only difference is that it crashes at char 3915 instead of 4041. Sorry, but not gdb hence no backtrace. ------------------------------------------------------------------------ [2002-09-17 07:56:38] [EMAIL PROTECTED] And I can still reproduce it with the short script and using latest CVS. (which has the new pcre lib) ------------------------------------------------------------------------ [2002-09-17 07:10:20] [EMAIL PROTECTED] I didn't see that Jani reproduced this. FWIW, I can not reproduce using current CVS or with PHP 4.2.1 (the oldest version I had to hand just now) using the short script that you provided. ------------------------------------------------------------------------ [2002-09-17 07:03:48] [EMAIL PROTECTED] Thank you for this bug report. To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes. To find out how to generate a backtrace, please read http://bugs.php.net/bugs-generating-backtrace.php Once you have generated a backtrace, please submit it to this bug report and change the status back to "Open". Thank you for helping us make PHP better. Could you supply a backtrace? Also, could you try with a non-stable snapshot from the last couple of days as the PCRE library was updated recently. ------------------------------------------------------------------------ [2002-09-17 05:22:14] [EMAIL PROTECTED] Tests of different lengths of string '$x' show that if strlen($x) > 4040 the crash occurs i.e. with the last text is 'Randomized-Controlled-Trial' php will crash. A shorter script as requested is: <?php $x = ''; while (true) { $x .= '*'; $len = strlen($x); preg_match('/(.|[\r\n])+/', $x, $match); echo "<br />$len\n"; } ?> ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
