#27735 [Com]: restart of apache2 via kill -1 or apachectl causes crash

ID: 27735 Comment by: noackjr at alumni dot rice dot edu Reported By: as at netoholic dot de Status: Bogus Bug Type: Reproducible crash Operating System: Linux PHP Version: 4.3.5 New Comment: This wasn't "Bogus", as expected. It's fixed in CVS according to Bug 27810: http://bugs.php.net/bug.php?id=27810 Previous Comments: ------------------------------------------------------------------------ [2004-03-31 05:53:04] js at iksz dot hu Nor FreeBSD, nor Linux libc checks whether regfree() got a null pointer. These bugs should be filtered in libc level. ------------------------------------------------------------------------ [2004-03-31 00:00:21] josestefan at hotmail dot com sorry, my report is wrong. I forgot that the error occurs after the first php request, when I did my testing. ------------------------------------------------------------------------ [2004-03-30 22:59:59] josestefan at hotmail dot com I've noticed that disabling all CustomLog in apache's httpd conf file avoids the crash. So maybe that's a good place for the developers to start looking. I have log_errors = Off on my php.ini file, so it really doesn't make sense to me. But I have confirmed that with the CustomLogs disabled, I get no crashes. running Windows XP, Apache: 2.0.49, PHP: 4.3.5 ------------------------------------------------------------------------ [2004-03-30 08:50:43] noackjr at alumni dot rice dot edu I have this exact same problem (identical backtrace, etc.) with FreeBSD 5.2.1, Apache 2.0.49, and PHP 4.3.5. Reverting to the PCRE from 4.3.4 (replacing ext/pcre) also resolved the problem for me. Does PCRE 4.5 expose an Apache bug, or is this a problem with PCRE 4.5? If it's the former, leave it as Bogus. Otherwise, this is a PHP bug because it's bundled code. ------------------------------------------------------------------------ [2004-03-30 06:57:35] chb at muc dot de I don't think this bug is "Bogus". I'm experiencing the same problems using Apache 2.0.49 with RedHat Linux 8.0 (same backtrace, ...). So far I've been able to track it down to the PCRE extension. When I add "--without-pcre" everything is fine. I've now replaced "ext/pcre", using the version from PHP 4.3.4 (PCRE 4.3) and the problem is gone. My suspicion is that the new PCRE version has memory allocation problems. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
