#44554 [Opn-Fbk]: *** glibc detected *** double free or corruption when using sqlite handler
ID: 44554 Updated by: j...@php.net -Summary: *** glibc detected *** double free or corruption Reported By: vlada at mysh dot cz -Status: Open +Status: Feedback Bug Type: Session related Operating System: Debian etch or lenny PHP Version: 5.2.12 Assigned To: fb-req-jani New Comment: Just to clarify: you are using your own compile and not any debian package? And no 3rd party patches are applied? Previous Comments: [2010-01-17 15:22:28] vlada at mysh dot cz After a year, I came to same problem on newer server.. There were a lot of warnings in apache's error_log *** glibc detected *** /usr/local/apache/bin/httpd: double free or corruption (out): 0x08b11590 *** *** glibc detected *** /usr/local/apache/bin/httpd: double free or corruption (out): 0x08b12a78 *** *** glibc detected *** /usr/local/apache/bin/httpd: double free or corruption (out): 0x08b1aa30 *** *** glibc detected *** /usr/local/apache/bin/httpd: double free or corruption (out): 0x0a399120 *** *** glibc detected *** /usr/local/apache/bin/httpd: double free or corruption (!prev): 0x0a3eab68 *** etc.. Mainly while using DokuWiki or phpMyAdmin After I changed session handler from sqlite to files, problem dissapeared. Now it's a week with files session handler and no new entry in log saying something about glibc error. So I am sure, it's caused by sqlite session handler. [2008-04-03 21:06:00] j...@php.net If you can reliably prove it's sqlite session handler that causes it, please reclassify this report as Session related and update the summary. [2008-04-03 18:40:26] vlada at mysh dot cz So.. I have checked configuration of PHP. Default php.ini-dist worked, so I make diff between mine and default. Main difference was in method of saving sessions. We were using sqlite. When I changed it to default, files type, everything is now OK. I leave this, files session configuration run for a longer period, but I think, problem was i sqlite. [2008-04-02 10:20:58] j...@php.net If you have 2 servers and on one you don't have such problems and on the other one you have, just check what the differences are in those systems. php.ini, configure lines, compiler versions, etc. [2008-04-02 10:13:43] vlada at mysh dot cz So.. I've sucessfully downgraded to same glibc version as on other server is. Than recompiled apache and php again with this older libc, but this errors appears in log again. Sometimes it causes exit signal Segmentation fault(11) and sometimes only exit signal Aborted (6). *** glibc detected *** double free or corruption (out): 0x08408b78 *** *** glibc detected *** double free or corruption (!prev): 0x0840d220 *** I am sorry for bothering but I going to be quite desperate about this problem, because I still don't know why it happens.
