ID: 36884 Comment by: tuliogs at pgt dot mpt dot gov dot br Reported By: guenther dot unterrainer at gknsintermetals dot com Status: No Feedback Bug Type: Apache related Operating System: SLES9 SP3 x86-64 PHP Version: 4.4.2 New Comment:
As noted in the notes for Oracle Funcions online documentation, this issue was already solved in PECL oci8 1.2.1 and later, but is still present in 4.4.7. To solve this, you´ll have to go through the following steps (modified from Rainer Klier´s notes on that page): 0. (before anything): be sure to have the path to instantclient in your LD_LIBRARY_PATH 1. download latest oci8-package from http://pecl.php.net/package/oci8 (if you already have PHP installed), just do "pecl download oci8" 2. extract package somewhere 3. go to php-4.4.x-source directory 4. rm -rf ext/oci8 5. cp extraceted oci8-1.2.x directory to/as ext/oci8 6. make distclean 7. If you use autoconf 2.5 and later (maybe other versions too), present in updated RedHat/CentOS 4.4 and 5, you MUST delete PHP´s configure script, or it will do nothing: rm configure 8./buildconf --force 9. ./configure (with the options you need) --with-oci8=instantclient,/path/to/instantclient (notice you´ll be using PHP5 syntax for --with-oci8) 10. make 11. ONLY for x86_64, and not really mandatory (same effect as manually editing "memory_limit = 128M" in php.ini, if existing): 11.1. create pear-install.ini: ----------------------------------------------- [PHP] memory_limit = 128M ------------------------------------------------ 11.2. edit Makefile: replace: PEAR_INSTALL_FLAGS = -n -dshort_open_tag=0 -dsafe_mode=0 with: PEAR_INSTALL_FLAGS = -cpear-install.ini -dshort_open_tag=0 -dsafe_mode=0 12. make install 13. if not already, set LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/path/to/instantclient" in your environment (one of profile, apachectl, or /etc/rc.d/init.d/httpd scripts, as you prefer) BEFORE starting Apache. No need to set TNS_ADMIN and tnsnames.ora for Instant Client, IF and only if Oracle´s easy syntax is available - see http://download-east.oracle.com/docs/cd/B12037_01/network.101/b10775/naming.htm#i498306 14. have fun! One example of easily reproducing sample for this issue is phpBB-3.0-RC1. I know it´s not small, but it´s very easy and simple to pick, and you´ll probably get this kind of error still in the install screens, past the database settings. Now I think it´s past time to update oci8, ;) this bug is really more than just an annoyance. *Note: presently, oci8 v1.2.3 may cause the following warning in some scripts: "ocilogoff(): supplied resource is not a valid oci8 connection resource in /path/to/script", but this is less troublesome and easily treated with adjusting logging facilities in php.ini while the scripts are adjusted.

I stored compressed data in TEXT field, but data was 85Kb length and was truncated to 65535. I think gzuncompress cause that glibc errors. After altering field to LONGBLOB problem gone. Good luck! ------------------------------------------------------------------------ [2006-10-11 14:01:11] kutovoy at gmail dot com The same errors on big arrays of objects. on PHP 4.4.2, I'm now trying to figure out working version of PHP. *** glibc detected *** free(): invalid pointer: 0x08925b00 *** [Wed Oct 11 09:26:06 2006] [notice] child pid 2610 exit signal Aborted (6) [Wed Oct 11 09:28:38 2006] [error] [client 194.247.xxx.yyy] File does not exist: /xxx/htdocs/yyy/favicon.ico [Wed Oct 11 10:58:43 2006] [notice] child pid 4059 exit signal Segmentation fault (11) and similar with *** glibc detected *** corrupted double-linked list: ------------------------------------------------------------------------ [2006-10-05 21:14:55] ndickerson at gmi-mr dot com I have also encountered this bug on php 4.3.10 using php xmlrpc libraries(phpxmlrpc.sourceforge.net) and processing an array of 20,000 records using the library, which happens to create a large number of objects. *** glibc detected *** double free or corruption (!prev): 0x0fbf24b8 *** is followed by some *** glibc detected *** corrupted double-linked list: 0x006f4858 *** There are also some other errors that I have lost that occur in the place of the double free or corruption error.. This works fine when it is not processing as many objects. ------------------------------------------------------------------------ [2006-10-05 16:53:12] egon at inf dot ufpr dot br The above code works fine in 5.1.
