#43528 [NEW]: gzdeflate - "buffer error" or just "segfault"

From: mi+php at aldan dot algebra dot com Operating system: FreeBSD/amd64 PHP version: 5.2.5 PHP Bug Type: Zlib Related Bug description: gzdeflate - "buffer error" or just "segfault" Description: ------------ I'm setting up MediaWiki-1.11.0, which uses gzdeflate (if available) to compress "serialized" objects. Every once in a while I would get either a: PHP Warning: gzdeflate() [<a href='function.gzdeflate'>function.gzdeflate</a>]: buffer error in /opt/www/mediawiki/includes/BagOStuff.php on line 374 or simply a report about httpd-child segfaulting in the server's error-log. I ended up commenting out the gzdeflate-detecting logic in MediaWiki's file in order to /never/ compress the objects, but that, obviously, is not a fix. I'm struggling to convince the server, that it is Ok to dump a core-file -- so I can not post a trace at the moment. But if you are aware of this problem already, however, I'd greatly appreciate a fix. -- Edit bug report at http://bugs.php.net/?id=43528&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=43528&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=43528&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=43528&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=43528&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=43528&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=43528&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=43528&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=43528&r=needscript Try newer version: http://bugs.php.net/fix.php?id=43528&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=43528&r=support Expected behavior: http://bugs.php.net/fix.php?id=43528&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=43528&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=43528&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=43528&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=43528&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=43528&r=dst IIS Stability: http://bugs.php.net/fix.php?id=43528&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=43528&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=43528&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=43528&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=43528&r=mysqlcfg
