php-5.2.5 glic detected

["php@xxxxxxxxxxx" <php@xxxxxxxxxxx>]

Hello all

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

Config:
# cat /proc/version
Linux version 2.6.24-rc7-vs2.2.0.5.0.7 (root@etch) (gcc version 4.1.2 
20061115 (prerelease) (Debian 4.1.1-21)) #2 SMP

# gcc --version
gcc (GCC) 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)

# dpkg -l libc6
libc6                       2.3.6.ds1-13etch5

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-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 made a mistake during php configuration but can't find where.

Any help/idea please ...

If you need more info, i can provide them

Thanks
