[HS?] php segfault libselinux.so.1 sur debian stable

[Julien <julien@nura.eu>]

Bonjour a tous, 

J'obtiens un 'segfault' à chaque fin de chaque exécution de processus
php :

glee:~# php -a
Interactive mode enabled

<? echo "Bonjour"; ?>
BonjourSegmentation fault
glee:~# 

La machine vient d'être installé, pas de pb sur la RAM ou sur les
disques dur... 

Comment faire pour voir d'où vient le problème ?

Merci d'avance, 
Julien
