Apache Segfault when accessing to /wp-admin/

Hi,

When i setup a fresh install (or using existing previously working wordpress website), after the setup, i try to go on the administration panel (wp-admin) and I have a beautiful segfault.

I have plenty of other website (they are based on PHP (without wordpress) that are working well. It only affect the backend of a WP site.

I have a really good server based on Debian (quadcore / 8Go DDR / 2Go php.ini limit)

When running apt-get update / upgrade. Everything is uptodate.

Here’s the PHP.INI

Here are some dumps :

PS: I do not have any .htaccess for wordpress cause i have full access of my server
