Hello all I got "glibc detected" errors about several php extensions on my debian box both by executing php-cgi or php-cli.

I'm running on debian-etch stable/backports. I build php-5.2.5 with this configure line: ./configure --enable-bcmath --enable-calendar --enable-exif --enable-ftp --enable-shmop --enable-soap --enable-sockets --enable-sysvmsg --enable-sysvsem --enable-sysvshm --enable-memory-limit --enable-wddx --enable-fastcgi --enable-dio --enable-dmalloc --enable-force-cgi-redirect --enable-discard-path --with-gmp=shared,/usr --with-gettext=shared,/usr --with-mysql=shared,/usr --with-pdo-mysql=shared,/usr --with-mysqli=shared --with-gd=shared --with-jpeg-dir=/usr --with-png-dir=/usr --with-zlib --with-zlib-dir=/usr --with-xpm-dir=/usr --with-freetype-dir=/usr --with-libt1=/usr --enable-gd-native-ttf --with-pgsql=shared,/usr --with-pdo-pgsql=shared,/usr --with-curl=shared,/usr --with-curlwrappers --with-xsl --with-xmlrpc --enable-xslt --with-xslt-sablot=/usr --with-mhash=shared,/usr --enable-dba=shared,/usr --with-gdbm=/usr --with-db4=/usr --with-cdb --with-mm=/usr --with-bz2=shared,/usr --with-imap=shared,/usr --with-kerberos --with-imap-ssl --with-readline --with-pcre-regex --enable-pcntl --enable-simplexml --enable-ctype --with-ming=shared,/usr --with-ncurses=shared,/usr --enable-mbstring --with-inifile --with-flatfile --with-iconv --with-ldap=shared,/usr --enable-gd-native-ttf --with-dom=/usr --with-dom-xslt=/usr --with-dom-exslt=/usr --with-expat-dir=/usr --with-zip=shared,/usr --with-openssl=/usr --with-snmp=shared,/usr --with-ttf=shared,/usr --with-libxml-dir=/usr --enable-dbase --enable-dbx --enable-dio --enable-filepro --enable-sqlite-utf8 --with-mcrypt=shared,/usr --with-pspell=shared,/usr --with-unixODBC=shared,/usr The errors occurs when i want to activate several shared extensions: pgsql, snmp, mcrypt. I'm really confused because if i build these extensions statically all works fine ( ./configure ..blabla... --with-pgsql ... --with-mcrypt ) I've a little script script to test pgsql connection : <? $dbconn = pg_connect("host=192.168.0.230 port=5432 user=demo password=demo dbname=demo"); $query = pg_exec ($dbconn, "SELECT * FROM agenda"); .... ?> If i call this script via a web browser i got in apache log: [Fri Feb 22 21:40:30 2008] [error] [client 192.168.0.22] *** glibc detected *** free(): invalid pointer: 0xb6b3f880 *** [Fri Feb 22 21:40:30 2008] [error] [client 192.168.0.22] Premature end of script headers: listepg.php If i call this script on command line, same error: etch:/web/clients/client1/www# php -c ../php.ini listepg.php connexion*** glibc detected *** free(): invalid pointer: 0xb48b8280 *** Abandon I'm knocking my head on the walls since several months about this issue which i didn't meet with previous versions of php (i compile myself since php-5.0.0RC1). All was working fine until i upgrade to php-5.2.x. More strange: i've installed php-xxx.deb from dotdeb packages (added in my sources.list) where these extensions are shared and in this case all works fine. I've asked dotdeb developper what may cause this issue on my box but he couldn't spent many time to debug my problem. In doubt, i've reinstalled all libxxxx-dev invoked by configure script but always same error. I've tried on 2 others machines with same distro and i got same error, too. I think i make a mistake during php configuration but can't find where. Any help/idea please ... If you need more info, i can provide them

Hello download the php-xxx.diff.gz from dotdeb source repo and see if there any differences in the debian/rules file from this diff to your configure options. The debian/control file has listed all the dependencies for build the php-xxx.deb packages. See also in this file for mistakes in your environment. Greetings Mario

Thanks for your answer Mario. I've effectively found many diff with dotdeb configure scripts. I will try a new compil next week and keep you informed. thanks again Patrick
